The Passionate Plumber is a 1932 American pre-Code comedy film directed by Edward Sedgwick, and starring Buster Keaton, Jimmy Durante, and Irene Purcell. The screenplay by Laurence E. Johnson and Ralph Spence is based on the 1926 play Dans sa candeur naïve by Jacques Deval. It is the second screen adaptation of the play, following the 1928 silent film The Cardboard Lover. It later was remade in 1942 as Her Cardboard Lover.

A French-language version was made at the same time, under the title, Le plombier amoureux.

The dueling sequence was reworked in two of Keaton's later short subjects, She's Oil Mine from 1941 and the 1947 Un Duel A Mort made in France.
