Cullen Landis (July 9, 1896 – August 26, 1975) was an American motion picture actor and director whose career began in the early ears of the silent film era.

James Cullen Landis was the middle of three siblings (two sons and a daughter) raised by Lulan and Margaret (née Cullen) Landis in Nashville, Tennessee, where his father supported his family as a stock broker. As a boy, James was a train enthusiast and dreamed to be an railroad engineer. Though the ambition eventually faded, his interest in railroads did not, and some years later he helped design for himself a model train set powered by steam. He began working in the fledgling film industry at age 18 around the time his older sister, Margaret Landis, appeared in her first film.
