Bumbershoot is an annual international music and arts festival held in Seattle, Washington. One of North America's largest such festivals, it takes place every Labor Day weekend at the 74-acre (299,000 m²) Seattle Center, which was built for the 1962 World's Fair. Seattle Center includes both indoor theaters and outdoor stages. The name of the festival was taken from , a colloquial term for umbrella, probably coined in the 19th century as a portmanteau of the words umbrella and parachute.
