Day of the Outlaw is a 1959 American Western film starring Robert Ryan, Burl Ives, and Tina Louise.

In spite of the fact that Helen has told him she can never love him if he carries out his threat to murder her husband, Starrett sets his mind on doing just that.

The film was based on a 1955 novel of the same title by Lee Edwin Wells (1907-1982), that also ran in several newspapers as a serialized story in the fall of 1955 and others in the late summer 1956.

[5] Filming took place in central Oregon at Dutchman Flat and Todd Lake Meadows near the town of Bend in late November and early December 1958, with Leon Chooluck, the second unit director, doing many of the long exterior shots.

Yordan told author Franklin Jarlett, in his biographical book about Robert Ryan, that de Toth was having personal problems at the time of filming and it was apparent on the set.
