Dean Tavoularis (born May 18, 1932) is an American motion picture production designer whose work appeared in numerous box office hits such as The Godfather films, Apocalypse Now, The Brink's Job, One from the Heart and Bonnie and Clyde. Although born in Lowell, Massachusetts, to Greek immigrant parents, Tavoularis spent his entire childhood and teenage years in Los Angeles, in the shadow of the Hollywood studios.

He studied architecture and painting at different art schools and landed a job at the Disney Studios first as an in-betweener in the animation department, and later as a storyboard artist. In 1967, Arthur Penn called him to take charge of the artistic direction of Bonnie and Clyde. Three years later, Penn called him once again to design Little Big Man.
