Emerald City Supporters (ECS) is an independent supporters group of Seattle Sounders FC founded in 2005. It is our mission to provide the best support in Major League Soccer, doing so by uniting supporters in their love of the Sounders. On matchdays, you can find many of us in the South End, pushing our boys onto victory through coordinated songs, flags, and large displays.
But regardless of where you support -- the 300 level at Lumen, on your couch, or across the country -- we welcome all members who aim to contribute to our mission. By joining ECS, you are ensuring that our traditions like the March to the Match, call and repeats, and the Boom Boom Clap remain and that our support for the Sounders continues to grow.




ECS is 100% member driven and funded, meaning we receive no financial support from corporate sponsors or the Sounders organization. It is the proceeds from our memberships that give us the opportunity to create the flags and large displays you see on matchday, as well as pre-purchase group tickets to provide our members with discounted tickets to all Sounders matches, home and away.
Above all, ECS is a community of diverse individuals that are united in their love of the Sounders. By becoming an ECS member, you are joining a close knit family that stands for equity, inclusion, and respect for all. When you wear your membership shirt and scarf, you are standing shoulder to shoulder with thousands of past and present members from around the world, joining your voice with theirs to lift our Sounders on to victory. You can stand proudly, knowing that you are continuing to write the legacy of the Emerald City Supporters, the best supporters in Major League Soccer.
Whether you are a diehard from seventy-four, a transplant looking for a place to call home, or visiting Seattle for the first time, come check out the Brougham End and GET TO KNOW YOUR NEIGHBOR.
