All in Love Is Fair is a studio album by American singer Nancy Wilson, released by Capitol Records in August 1974. It was her first album with producer Gene Page, who also did the arrangements and conducting and gave the album a more R&B-oriented sound. Musicians on the album include Ray Parker Jr., Wah Wah Watson, and Tom Scott. Marvin Gaye is also listed on the back cover as "The Phantom," with "warmest thanks." All in Love Is Fair includes one of the few songs co-written by Wilson.
