Who will bring the noise? The top 10 most passionate fanbases at the 2026 World Cup – ranked

The 2026 World Cup will unite millions of supporters across the United States, Canada and Mexico, creating what could be one of the loudest, most vibrant tournaments football has ever seen.

With 48 nations competing across three vast host countries, the atmosphere is set to become just as memorable as the football itself.

World Cups are often defined by supporters, with some fanbases known for relentless singing, others for colour and choreography, and a few travel in such huge numbers that they transform entire cities into home grounds.

With that in mind, FootballGroundGuide ranks the ten fanbases most likely to dominate the noise, colour and chaos across North America this summer.

10. United States

One of the co‑hosts open the list.

Football culture in the US has transformed over the past two decades, with MLS supporter groups introducing organised singing, flags, drums and matchday traditions that didn’t exist a generation ago.

The home‑advantage factor also matters. Even neutral fixtures are likely to feature a strong American presence, with stadiums across the country filling up regardless of who is playing.

9. Portugal

Part of Portugal's strength comes from its global reach.

The Cristiano Ronaldo effect still carries enormous influence, and Portuguese supporters consistently travel in impressive numbers for major tournaments.

Add to that the large Portuguese communities in Boston, Newark and Toronto, and several World Cup venues could feel unexpectedly close to home.

8. Scotland

The return of Scotland to the World Cup for the first time since 1998 will instantly improve the atmosphere.

The Tartan Army is widely regarded as one of football’s great travelling fanbases, bringing humour, kilts, bagpipes and non‑stop singing wherever they go.

At Euro 2024, they were among the tournament’s most visible groups, regardless of results on the pitch, so expect Boston, Toronto, Vancouver and New York to be covered in navy blue.

7. Japan

Japanese supporters create atmosphere differently.

Rather than constant chaos, their reputation comes from highly organised chanting, coordinated tifos and incredible visual displays.

Their supporters are also known for remaining in stadiums to help clean up after matches.

At recent tournaments, they have consistently travelled in large numbers and produced some of the most visually striking support.

6. Colombia

Colombia’s supporters help bring football and carnival together.

Drums, dancing and waves of colour helped make them one of the standout fanbases at the 2014 and 2018 World Cups. They also have a reputation for taking over stadiums far from home, turning neutral venues into yellow‑and‑red cauldrons.

Large Colombian communities in Miami, Houston and New York should only amplify their presence.

5. England

England remain one of football’s biggest travelling fanbases.

Whether it is city‑centre pubs, hours‑long chanting or huge gatherings in fan zones, England supporters have shaped the atmosphere at almost every major tournament for decades. Their presence is impossible to ignore.

With East Coast host cities including Boston, New York and Philadelphia, travelling numbers could be enormous.

4. Morocco

Morocco’s run to the 2022 World Cup semi‑finals elevated both the team and its supporters to new global prominence.

The Atlas Lions fanbase is famous for drums, chanting and relentless energy, while large Moroccan communities in Europe and North America could create significant support at multiple venues.

New York and Toronto, in particular, could be transformed if Morocco make another deep run.

3. Brazil

There are few fanbases more recognisable than Brazil.

Yellow shirts, samba drums and dancing crowds have become part of World Cup folklore – even during long waits for another world title, Brazilian supporters continue to travel in huge numbers.

Watching Brazil in person remains a bucket‑list experience for many neutrals, adding to the noise and spectacle.

2. Mexico

You would imagine that Mexico will feel almost like a home nation across the entire tournament.

“El Tri” supporters have consistently been among the loudest at previous World Cups and travel in vast numbers.

With matches in Mexico City, Monterrey and Guadalajara, plus huge Mexican communities across the US, the atmosphere could be dominated by green shirts from start to finish.

1. Argentina

Defending champions, global icons and potentially one final World Cup involving Lionel Messi.

Argentina’s supporters mix emotion, passion and relentless chanting in a way few fanbases can match. Their support rarely pauses, creating one of football’s most intense and immersive atmospheres.

Combine that with huge South American support across North America and the possibility of Messi’s final World Cup, and Argentina could become the soundtrack of the entire tournament.
