William Pitt Striker Earle (December 28, 1882 – November 30, 1972) was an American director of the silent film era.
He attended Columbia University and worked for a time as a photographer before breaking into the movie business by sneaking onto the lot of Vitagraph Company of America to observe how directors worked.
After a few days of this, Earle approached the studio president and was given his first movie to direct, For the Honor of the Crew, a short about a crew race at Columbia University.
He subsequently directed a number of features and shorts for Vitagraph.
