All in Love Is Fair is a studio album by American singer Nancy Wilson, released by Capitol Records in August 1974.

Marvin Gaye is also listed on the back cover as "The Phantom," with "warmest thanks.

Jason Ankeny at AllMusic hails Wilson's "sultriness and soulfulness.

Page swaddles the singer in billowing strings and slow-burn funk rhythms, weaving a series of luminously sensual backdrops that wouldn't be out of place on Motown or Philadelphia International."

He also notes that "the music never veers so far into the mainstream that Wilson abandons her jazz roots entirely, and she brings to the songs the intelligence and articulateness one would expect.
