A supporters group is a community of fans who come together to cheer on their team in an organized, energetic, and engaged way.

Not only do they create an electric atmosphere at games with chants, flags, songs, and coordinated cheering but supporters groups often do more than just attend matches—they engage in social events, charity work, and help promote the team and the sport within their local communities.

Short answer: Nope!

Longer answer: Boston ISA is an independent, fan-run association.

We are not affiliated with or controlled by the Boston Legacy FC franchise.

While we certainly root for the team, we operate separately - making our own decisions and working solely to promote the best interests of our members.

All adults 18+ in the US are able to join the ISA. You must abide by our code of conduct, and those of the team and league to remain in good standing. More details about those codes can be found here.

We do charge an annual membership fee. This fee funds group activities, tifo creation (those big banners you see at some games), start-up expenses, and will help to offset the cost of organizing member events. To learn more and join, click on the Join link in the toolbar above.

The inaugural season is all about continuing to build our community through regular meet-ups, watch parties, tailgates, volunteerism, and other social events.

The benefits and perks are growing as we grow, and we will start to keep a clear list on our website and communicate new perks, partners, and other benefits through our communications channels.

The biggest benefit to being a member right now is to be part of building this wonderful community from the ground up!

We welcome fans of all levels—whether you're a lifelong soccer supporter or just learning about the team.

• Not sure how the offside rule works?
  We are happy to explain it.

• Worried a 3-back system might be risky against a team like Gotham?
  We understand your concern.

Boston ISA is for every kind of fan, and we can't wait to meet you!

Boston Legacy FC has announced that their homes for the 2026 season will be Gillette Stadium in Foxboro, MA and Centreville Bank Stadium in Pawtucket, RI.

For 2027 and beyond, the team expects to call White Stadium in Boston, MA their home field.

We are very excited about a revitalized White Stadium, and are thrilled to see the city has signed a 10-year lease agreement with the team.

If you would like to learn more, or get involved in the process, a great place to start is the city’s project page or the Legacy’s page, here.
