The Seahawks “12” refers to the team’s fans, known as the 12s , who are treated as the “12th player” on the field because of how loud and passionate they are during games.

What does the Seahawks 12 mean?

  • “12” (or “12th Man,” now usually just “12s”) is the nickname for Seattle Seahawks fans.
  • The idea is that there are 11 players on the field, and the crowd’s energy acts like a 12th player by boosting the Seahawks and disrupting opponents.
  • The team even retired jersey number 12 in honor of the fans, which is rare in pro sports.

How the 12s show up on game day

  • At home games, you’ll see lots of No. 12 jerseys, flags, and signs all over Lumen Field and around Seattle.
  • Crowd noise from the 12s is famous for being extremely loud and has even set records, making it harder for visiting teams to communicate.
  • One legendary example is the “Beast Quake” run by Marshawn Lynch, where the crowd got so loud it registered as a small earthquake on local instruments.

A bit of background and culture

  • The “12th Man” concept in football goes back to college traditions (notably Texas A&M), but Seattle built its own identity around it and popularized “12s” as the fan label.
  • The Seahawks introduced a 12 flag that’s raised before games as a symbolic thank-you to the fans.
  • Around Seattle, you’ll see the number 12 on buildings, cars, and homes, especially during big playoff runs, as a sign of community pride and support.
