Yale Thomas Boss (October 18, 1899 – November 16, 1977) was an American child actor of the silent screen.
A native of Utica, Oneida County, New York, Boss was one of the screen's first child stars and a stage veteran when he made his screen debut in Thanhouser's The Actor's Children. He appeared on Broadway opposite Adeline Geneé in The Silver Star.
Later he became Edison's most popular players but the studio constantly had to battle rumors questioning his true age. Boss' popularity waned in the late 1910s and he later worked as a prop man. By the time of his death at age 78, the former actor was operating a garage in Augusta, Richmond County, Georgia. He is buried in Westover Memorial Park, Richmond County, Georgia, USA.
