The Ninety Day Mistress is a 1967 sex comedy play. The original production starred Walter Abel, Martin Milner and Dyan Cannon and ran for 24 performances.^[1][2]

The play was profiled in the William Goldman book The Season: A Candid Look at Broadway. Goldman argued the play "hand enough laughs to succeed. What killed it, I think, was that it was a masquerade and not well enough disguised: the notion of constantly compulsively changing partners because it gets so dull if you don’t is basically a homosexual one, and I think the play was basically a homosexual play." Goldman said "if the girl had been cast as a boy, the play might have worked... People are always talking about how they'd like to see Virginia Woolf and Streetcar done all male. I'd like to add Ninety-Day Mistress to the list."^[3]
