Mabel's Blunder (1914) is a silent comedy film directed by, written by, and starring Mabel Normand, the most successful of the early silent screen comediennes.

Mabel's Blunder tells the tale of a young woman who is secretly engaged to the boss's son.

Produced at Mack Sennett's Keystone Studios, known at the time as "The Fun Factory", Mabel's Blunder showcases Normand's spontaneous and intuitive playfulness and her ability to be both romantically appealing and boisterously funny.

This film, with its unusual gender-bending aspect, was added to the National Film Registry by the Library of Congress in December 2009 for being "culturally, historically or aesthetically" significant.
