My Favorite Duck is a 1942 color Warner Bros. Looney Tunes cartoon directed by Chuck Jones, in his second collaboration with writer Michael Maltese. The cartoon was released on December 5, 1942, and stars Daffy Duck and Porky Pig. It was the second color entry in the Looney Tunes series, and the first pairing of Porky and Daffy produced in Technicolor.

The title was presumably inspired by a film of that era, either My Favorite Wife (1940) or My Favorite Blonde (1942). In this case the title is used ironically. This is one of several entries in a series where Daffy (during his "screwball" period) torments Porky in a variety of ways.
