The Seattle Cossacks are a motorcycle stunt and drill team that was founded in 1938. Named after Russia's famous calvary, the members named themselves the Seattle Cossacks due to their similar mastery of motorcycles, or "iron horses." Except for a few years during World War II, the team has regularly performed since the late 1930s, and is still active as 2025.
