Her Wild Oat is a 1927 American silent comedy film made by First National Pictures, directed by Marshall Neilan, and starring Colleen Moore.

The screenplay was written by Gerald C. Duffy, based on a story by Howard Irving Young.

[2] This was Moore's first film after a contract dispute between her, her husband John McCormick, and her studio First National caused the couple to suddenly leave California for New York, with the intentions of making films either with another studio or going overseas.

Her Wild Oat was a simple story (originally racier until rewritten by Neilan to play up the comic aspects), and could be shot entirely in California, mostly on location and using existing sets.

Marshall also produced Social Register (1934) with Moore, one of her last four films before retiring from Hollywood.
