"Une femme avec une femme" (Spanish: "Mujer contra mujer") is a 1990 song by Spanish pop band Mecano. In the late 1990, it was released as a single from the band's seventh album, released in 1988, Descanso dominical, on which it appears as the third track. It became a hit in France, hitting number one for seven weeks. Also in 1990, the song was notably covered by the pop duo formed by Argentine singers Sandra Mihanovich and Celeste Carballo as the title track of their studio album Mujer contra mujer, which is regarded as a landmark by the country's lesbian community.
