Down with Love is a 2003 romantic comedy film. It was directed by Peyton Reed and stars Renée Zellweger, Ewan McGregor, Sarah Paulson and David Hyde Pierce.

The story follows a woman who advocates female independence in combat with a lothario and the patriarchal, even male chauvinist society of the 1950s and early 1960s. The film is a pastiche of the sex comedies that were popular in the era in which Down with Love is set, in particular the three films that starred Doris Day and Rock Hudson: 1959's Pillow Talk, 1961's Lover Come Back and 1964's Send Me No Flowers.
