Edgar Buchanan (March 20, 1903 – April 4, 1979) was an American actor with a long career in both film and television, most familiar today as Uncle Joe Carson from the Petticoat Junction, Green Acres and Beverly Hillbillies television sitcoms of the 1960s. As Uncle Joe, "who is moving kinda slow", he took over as proprietor of the Shady Rest Hotel following the death of Bea Benaderet, who had played Kate Bradley.

At the age of seven, he and his family moved to Oregon. After studying at the University of Oregon, he followed in his father's footsteps and became a dentist, graduating from North Pacific Dental College. From 1929 to 1937 he was the practiced oral surgery in Eugene, Oregon. He then moved his practice to Altadena, CA. There he joined the Pasadena Community Playhouse, eventually giving up dentistry at the age of 36 to become an actor. He made his film debut in 1939. His chubby face and gravelly voice were featured in over 100 films, but he is perhaps best known for TV roles in "Judge Roy Bean" (1956), "Petticoat Junction" (1963), and "Cade's County" (1971).
