Cheaper to Keep Her is a 1981 American comedy film directed by Ken Annakin, which starred singer-turned-actor Mac Davis alongside Tovah Feldshuh.

William "Bill" Dekker (Davis) is a newly divorced swinger who goes to work for an attorney named K. D. Locke (Feldshuh) as an investigator.

Leonard Maltin rated it a BOMB, while the reviewing duo of Mick Martin and Marsha Porter labeled it a turkey.

Gene Siskel, who registered the film for a "Dog of the Week" segment on PBS' Sneak Previews,[2] called it "a pathetic comedy" with misleading advertising, adding: The comedy is lame, the sex is childish, and the only reason the film has an "R" rating is because of a single swear word.

"Cheaper to Keep Her" is a cheaply made, sloppily photographed comedy that isn't even on a par with the few made-for-TV movies I've seen.
