Fatty's Tintype Tangle is a 1915 comedy short film (2 reel). A man (Fatty), tired of his mother-in-law's henpecking, leaves home in anger and sits on a park bench, where a photographer takes a picture of him sitting next to a married woman, whose husband is not pleased. Conflict ensues.

The movie stars Roscoe "Fatty" Arbuckle (who also directed), Louise Fazenda, Edgar Kennedy, Minta Durfee and Frank Hayes. Arbuckle performs several feats of dexterity in the first few minutes and, near the end, runs and bounces on 17 closely spaced apparent telephone wires over 20 feet (6 m) above the ground.

In 1995, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant." It has often been shown on Turner Classic Movies.
