We are Boston ISA, an independent supporters association rallying around our shared support for Boston Legacy FC.

Yeah, yeah, we know… the team won’t even take the field until 2026, and we're currently a supporters group without a real name, but there is so much to do, and we are wicked excited to get started!

We are gearing up by building a community of supporters that’s loud, proud, and ready to welcome the NWSL back to Boston in style!

In 2025, we have been getting together to watch soccer, getting to know each other, writing chants, and generally getting ready to bring the kind of energy that’ll shake the stands.

Maybe they don’t know it yet, but Boston Legacy FC is about to have the most passionate, engaged supporters in the league! Whether you’re a longtime soccer fan or planning on attending your first match next year, there’s a place for you in our supporters group.

2025 Founding Memberships are now closed, but 2026 memberships will launch on January 5th!

We are about to show the world how we do things in the City of Champions.

Let’s go, kid!
