A Coy Decoy is a 1941 Warner Bros. Looney Tunes cartoon, directed by Bob Clampett. The cartoon was released on June 7, 1941, and stars Porky Pig and Daffy Duck.

The film is set in a closed bookstore at night, when the many characters and elements featured within the books come to life, similar to Frank Tashlin's own shorts Speaking of the Weather, Have You Got Any Castles?, and You're an Education. The idea would later be reworked five years later into Book Revue, although only Daffy features in that.
