Jason Sprinkle (November 6, 1969 - May 16, 2005) was a Seattle-based sculptor and guerrilla artist.
He was most famous for attaching a 700-pound ball and chain around the foot of Jonathan Borofsky's Hammering Man outside of the Seattle Art Museum and for various other illegal art sculptures left at Westlake Park.
These actions ended in July 1996 when Sprinkle's final sculpture caused a bomb scare and Sprinkle was briefly imprisoned.
After suffering a mental breakdown in jail, Sprinkle stopped making art and became a born again Christian.
