Daniel Haller (born 1926 in Glendale, California) is an American film and television director, production designer, and art director.

In 1953, Haller started as an art director in television, then quickly graduated to low budget feature films. Among many other credits, Haller designed the deceptively opulent sets for nearly all of Roger Corman's critically acclaimed Edgar Allan Poe film series, including House of Usher (1960) and The Pit and the Pendulum (1961).

Haller directed his first film, Die, Monster, Die!, in 1965 for American International Pictures. Based on H. P. Lovecraft's short story The Colour Out of Space, it was very similar in plot and atmosphere to Corman's Poe films. After directing two motorcycle pictures (The Devil's Angels (1967) and The Wild Racers (1968)), Haller filmed another Lovecraft adaptation, The Dunwich Horror (1970).

From 1972, all of Haller's subsequent work has been in television.

Daniel Haller was born in Glendale, California, USA and received his own art training at the renowned Chouinard Institute. By chance, he happened to meet New World Pictures' Roger Corman in the mid-1950s when Corman was still an unknown, independent producer-director-jack-of-all-trades. Corman persuaded Haller to become an art director, a relationship which continued through some 30 Corman films. He later became a director, under Corman's banner, turning out such films as "Paddy", "Checkered Flag" and "Devil's Angels", with John Cassavetes. In 1971, he moved over to television, directing episodes of "Kojak", "Owen Marshall", and "The Blue Knight." as well as such movies-for-television as "Black Beauty" and "Little Mo." Haller lives in the western San Fernando Valley on a ranch with his family, where they raise horses.
