Robert North Bradbury (March 23, 1886 – November 24, 1949) (born Ronald E. Bradbury) was an American film actor, director, and screenwriter. He directed 125 movies between 1918 and 1941, and is best known for directing early "Poverty Row"-produced Westerns starring John Wayne in the 1930s, and being the father of noted "cowboy actor" and film noir tough guy Bob Steele.
Bradbury variously billed himself as "Robert North Bradbury", "R.N. Bradbury", or "Robert Bradbury". He died in Glendale, California, on November 24, 1949, at age 63.
