MLS Rivalries & Derbies

The Biggest MLS Rivalries Ranked: A Data-Driven Power Ranking

Ranking the biggest rivalries in MLS history using attendance data, cards, goals, historical significance, and fan intensity. From El Trafico to the Hudson River Derby.

Every great sports league is defined by its rivalries. The Premier League has Liverpool-Manchester United and the North London Derby. La Liga has El Clasico. Serie A has the Derby della Madonnina. For Major League Soccer, the rivalry landscape has evolved from manufactured marketing exercises into genuine, organic hatred — and the best MLS rivalries now generate the kind of atmosphere that can stand alongside anything in world football.

But which rivalries are actually the biggest? Not just the ones with the cleverest names or the most social media buzz, but the ones backed by data: attendance spikes, card counts, goal-scoring intensity, historical significance, and the intangible factor of fan hostility that turns a regular season match into something unforgettable.

Here is our power ranking of MLS's biggest rivalries, backed by the numbers and shaped by three decades of history.

How We Ranked Them

We evaluated each rivalry across five criteria:

  1. Attendance premium: Do these matches draw significantly more fans than each team's average?
  2. Intensity on the pitch: Cards (yellow and red), fouls, and goals per match relative to each team's baseline.
  3. Historical significance: How long has the rivalry existed? How many meaningful playoff and championship matches have occurred?
  4. Fan culture: Tifo, supporter group engagement, traveling fan presence, and atmosphere.
  5. Narrative weight: Do these matches matter beyond the table? Do they generate storylines that define seasons?

No single metric determines the ranking. A young rivalry with electric atmospheres (El Trafico) can rank above an older one that has lost intensity (some of the original-era matchups). The ranking reflects the state of each rivalry as of the 2026 season.

1. El Trafico: LA Galaxy vs. LAFC

First match: 2018 All-time series: Competitive and closely contested Average attendance premium: 30-40% above each team's regular average Cards per match: Among the highest in MLS

El Trafico is the best rivalry in MLS. Full stop. It is also the youngest on this list, which tells you everything about its intensity.

When LAFC entered MLS in 2018, the Galaxy — the league's most successful franchise with five MLS Cups — suddenly had to share Los Angeles. The Galaxy's fans viewed LAFC as upstarts. LAFC's supporters, anchored by the 3252, viewed the Galaxy as a fading legacy act. The mutual contempt was immediate and authentic.

The matches have delivered. The 2019 matchup in which Carlos Vela and Zlatan Ibrahimovic traded hat tricks in a 5-3 LAFC victory is one of the greatest regular season games in MLS history. The atmosphere at both Dignity Health Sports Park and BMO Stadium (formerly Banc of California Stadium) during El Trafico matches is genuinely hostile — in the best possible soccer sense.

What makes El Trafico number one is the combination of market size (Los Angeles), star power (both rosters consistently feature high-profile DPs), supporter culture (the 3252 vs. the LA Galaxy supporter groups), and on-field quality. These are not grudge matches between bad teams. They are grudge matches between talented teams in the biggest American media market.

The card counts tell the story. El Trafico matches average significantly more yellow cards than either team's overall average. Red cards are not uncommon. The tackles are harder, the time-wasting is more blatant, and the referees are more active. Both teams treat these matches as cup finals regardless of the standings.

2. Cascadia Cup: Portland Timbers vs. Seattle Sounders vs. Vancouver Whitecaps

First match: 2011 (MLS era; rivalry predates MLS by decades) Core matchup: Portland vs. Seattle Average attendance premium: 15-25% Atmosphere: Consistently the best in MLS

The Cascadia rivalry is the oldest continuous rivalry in American and Canadian professional soccer, predating MLS by decades. The Portland Timbers, Seattle Sounders, and Vancouver Whitecaps competed against each other in various lower-division leagues and the USL before all three joined MLS (Seattle in 2009, Portland and Vancouver in 2011).

The Portland-Seattle axis is the rivalry's core. The Timbers Army and Emerald City Supporters are two of the most organized, creative, and passionate supporter groups in North American sports. Their tifo displays, choreographed chants, and sustained 90-minute atmospheres are the gold standard for MLS.

The matches themselves are physical, tactical, and often decided by fine margins. The 2021 MLS Cup Western Conference rivalry in the playoffs between these two was a masterpiece of intensity. Portland's Providence Park and Seattle's Lumen Field (now often sold out for Sounders matches) produce atmospheres that visiting players regularly cite as the most intimidating in the league.

Vancouver is sometimes overshadowed in the Cascadia trio, but the Whitecaps' matches against Portland and Seattle carry significant weight in the Pacific Northwest. The cross-border dynamic adds a layer of national pride — Canada vs. United States — that other MLS rivalries lack.

The Cascadia Cup is ranked second because of its combination of longevity, authenticity, supporter culture, and consistent on-field quality. It loses the top spot to El Trafico only because the Los Angeles rivalry's star power and media market amplification edge it out in overall impact.

3. Hudson River Derby: New York Red Bulls vs. New York City FC

First match: 2015 Average attendance premium: 20-30% Cards per match: High

New York's soccer rivalry took a decade to materialize. The Red Bulls (formerly MetroStars) were MLS's sole New York-area franchise until NYCFC arrived in 2015, backed by City Football Group and the New York Yankees. The class dynamics were immediate: Red Bulls fans viewed NYCFC as a plastic, corporate project. NYCFC fans viewed the Red Bulls as a New Jersey team pretending to represent New York.

The derby has produced memorable moments. NYCFC's early years at Yankee Stadium — a baseball venue with a comically narrow soccer field — gave the matches a unique visual absurdity. The Red Bulls' dominance in the early head-to-head (they won several of the first derbies convincingly) gave way to a more competitive rivalry as NYCFC improved and eventually won MLS Cup in 2021.

What elevates the Hudson River Derby is the market. New York media coverage amplifies every narrative. Player quotes become bulletin board material. Managerial mind games play out in press conferences covered by the largest sports media apparatus in the country. The rivalry's intensity is as much about off-field narratives as on-field results.

4. Hell Is Real Derby: Columbus Crew vs. FC Cincinnati

First match: 2019 Named after: A roadside billboard on I-71 between Columbus and Cincinnati Atmosphere: Electric, especially at TQL Stadium

The Hell Is Real Derby might have the best name in American sports. Inspired by a roadside evangelical billboard on Interstate 71 — the highway connecting Columbus and Cincinnati — the rivalry was born when FC Cincinnati joined MLS in 2019.

Despite its youth, this rivalry has genuine organic roots. Ohio soccer fans had long debated which city was the state's true soccer capital. Columbus had MLS history (the Crew were a charter franchise). Cincinnati had fan energy (FC Cincinnati set attendance records in the USL before joining MLS). The first Hell Is Real Derby in 2019 drew over 30,000 fans to Nippert Stadium.

The rivalry has deepened as both teams have improved. The Crew's MLS Cup victories in 2020 and 2023 gave Columbus bragging rights. Cincinnati's 2023 Supporters' Shield win and their consistently packed TQL Stadium proved that the Crew no longer had a monopoly on Ohio soccer relevance.

The matches are intense, the card counts are elevated, and the traveling support is robust — Columbus and Cincinnati are only 100 miles apart, making away-day attendance feasible and common.

5. Atlantic Cup: New York Red Bulls vs. D.C. United

First match: 1996 Historical significance: The original MLS rivalry Playoff meetings: Multiple, including early-era finals

The Atlantic Cup is MLS's original rivalry. The Red Bulls (then MetroStars) and D.C. United have been playing each other since the league's first season in 1996. In the early years, when MLS had just ten teams and D.C. United was winning everything, these matches had genuine championship implications.

The rivalry peaked in the late 1990s and early 2000s, when D.C. United's dynasty clashed with the MetroStars' chaotic ambition. Players like Marco Etcheverry, Eddie Pope, Tab Ramos, and Clint Mathis added personal intensity. Playoff meetings were common and contentious.

The Atlantic Cup has lost some luster in recent years as both teams have cycled through rebuilding phases. Neither has been consistently elite in the 2020s, which diminishes the rivalry's current stakes. But the historical weight — 30 years of head-to-head matches, playoff history, and East Coast bragging rights — keeps it in the top five.

6. Texas Derby: FC Dallas vs. Houston Dynamo

First match: 2006 Geographic proximity: 240 miles (closest geographic rivalry in MLS for years) Historical wrinkle: Houston inherited San Jose's roster, including players who had played against Dallas

The Texas Derby carries a unique historical sting. When the San Jose Earthquakes relocated to Houston in 2006, they brought most of their roster — players who had genuine competitive history with FC Dallas. The rivalry was instant, fueled by state pride, geographic proximity, and the friction of a forced relocation.

The matches between FC Dallas and the Dynamo are consistently physical. The summer heat in Texas adds a survival element to these games that other rivalries lack. Card counts are elevated. Tempers flare.

What limits the Texas Derby's ranking is that neither team has been a consistent national contender in recent years. The rivalry matters deeply to fans in Dallas and Houston, but it lacks the national profile of the top five entries.

7. Cali Clasico: LA Galaxy vs. San Jose Earthquakes

First match: 1996 Historical significance: Original MLS rivalry between California clubs Current intensity: Diminished from its peak

The Cali Clasico is one of MLS's oldest rivalries, dating to the league's inaugural season. In the early years, when MLS had fewer teams and California was a soccer heartland, Galaxy-Earthquakes matches were among the most anticipated on the calendar.

The rivalry peaked during the Earthquakes' 2001 and 2003 MLS Cup-winning seasons, when Landon Donovan was tormenting the Galaxy (before eventually joining them). The competitive balance has since shifted dramatically in the Galaxy's favor, and San Jose's struggles in the 2010s and 2020s have reduced the rivalry's intensity.

The Cali Clasico still produces atmosphere — California soccer fans are passionate, and the geographic connection is real — but it needs both teams competing at a high level simultaneously to return to its peak.

8. Rocky Mountain Cup: Colorado Rapids vs. Real Salt Lake

First match: 2005 Geographic and cultural connection: Mountain West identity Atmosphere: Underrated

The Rocky Mountain Cup is the rivalry that national MLS media consistently underrates. The matches between Colorado and Real Salt Lake are intense, well-attended relative to both teams' averages, and meaningful to the fanbases in ways that do not always translate to national broadcast appeal.

The 2009 and 2010 seasons were the rivalry's high point: RSL won MLS Cup in 2009, and Colorado won it in 2010. Back-to-back champions from the Mountain time zone, both underdogs, both proving that MLS was not just a coastal league.

9. Cross-Iron Derby: CF Montreal vs. Toronto FC

First match: 2012 (MLS era) Cultural dimension: Quebec vs. Ontario, French vs. English Historical roots: Canadian Championship rivalry predating MLS

The Canadian rivalry between Montreal and Toronto carries cultural weight that transcends soccer. The Quebec-Ontario divide, the French-English language dynamic, and the broader Canadian identity question all inform this rivalry. When the Canadian Championship is at stake — with a CONCACAF Champions League berth on the line — these matches reach a fever pitch.

In MLS regular season play, the rivalry has been more subdued, partly because both teams have rarely been elite simultaneously. Toronto FC's 2017 treble-winning season (Supporters' Shield, MLS Cup, Canadian Championship) was the rivalry's modern peak, as Montreal watched their domestic rival claim everything.

10. El Trafico del Norte: San Jose Earthquakes vs. Sacramento Republic (Projected)

While Sacramento Republic has not yet joined MLS, the anticipation of a Northern California rivalry is worth noting. The NorCal soccer community has long awaited this matchup, and when Sacramento does arrive, the geographic proximity (90 miles) and existing USL-era fan cultures suggest it could quickly become a significant rivalry.

Honorable Mentions

  • Inter Miami vs. Orlando City (Florida Cup): Growing in intensity as both Florida clubs invest in their rosters. The Messi factor has given Inter Miami a star power edge that Orlando fans resent.
  • Atlanta United vs. Nashville SC: A Southeast rivalry that has potential but has not yet consistently produced memorable matches.
  • LAFC vs. Club America (Leagues Cup): The cross-border dimension of LAFC taking on Liga MX clubs in the Leagues Cup has created a new kind of rivalry that blurs domestic and international lines.
  • Seattle Sounders vs. LAFC: Not a traditional rivalry, but consistently the best regular season matchup in the Western Conference. Both teams respect each other, which actually reduces the rivalry's heat.

What Makes an MLS Rivalry Great

The best MLS rivalries share several characteristics that distinguish them from manufactured marketing exercises:

Geographic proximity: The strongest rivalries involve teams close enough for meaningful traveling support. El Trafico (same city), Cascadia (Pacific Northwest corridor), Hell Is Real (100 miles on I-71), and the Hudson River Derby (same metro area) all benefit from fans who can realistically attend away matches.

Cultural identity: Rivalries that tap into existing cultural or regional identities resonate more deeply. Cascadia's Pacific Northwest ethos, the Texas Derby's state pride, and Montreal-Toronto's Canadian bilingual divide all add layers beyond soccer.

Competitive balance: A rivalry where one team wins every time is not really a rivalry — it is a tradition of humiliation. The best MLS rivalries feature teams that trade dominance over time.

Supporter culture: Tifo, chants, songs, traditions — these are the elements that create atmosphere. Rivalries with strong supporter groups on both sides (El Trafico, Cascadia, Hudson River Derby) produce moments that transcend the 90 minutes on the field.

Stakes: Matches that determine playoff positioning, Shield races, or championship outcomes carry more weight. The best rivalries produce consequential matches regularly, not just when the schedule happens to align.

The Future of MLS Rivalries

As MLS continues to evolve, new rivalries will emerge and existing ones will shift. The 2026 World Cup may accelerate fan engagement in ways that intensify local rivalries. Expansion teams in new markets will create geographic pairings that do not yet exist.

But the core truth about MLS rivalries is that the best ones were never manufactured. They grew organically from geography, culture, competitive proximity, and the passion of supporters who decided that these matches mattered more than others. The league can name a rivalry and create a trophy for it, but it cannot create the hatred, the songs, the tifo, or the collective memory that turns a regular season match into an event.

That is earned. And the rivalries at the top of this list have earned it.
