Catherine Ringer born 18 October 1957, Suresnes, France is a French singer, musician, songwriter, dancer, choreographer, and actress.

Ringer started her professional career on stage in the late 1970s in productions with Michael Lonsdale's Theatre de Recherche Musicale as well as musical and dance productions.

In 1976 she met the Argentine dancer and choreographer Marcia Moretto with whom she studied and also performed in various venues in Paris. The hit song "Marcia Baila" was written as a tribute to Moretto after her death in 1981. On film, Ringer also performed in pornographic movies such as La Fessee (1976) and Body Love (1977). In 1979 she met Fred Chichin with whom she founded and co-led the music group Les Rita Mitsouko. Ringer continued leading the group after Chichin's death in November, 2007.

Catherine loved doing adult films and claims that some of the sex she had on set was some of the best sex of her life. People who watch her having sex say its because Catherine would feed on all the people watching her and getting off by her. Just the thought of her turning others on by watching would get her going and often she would be up for trying things she had never considered before. One example of that is while in the middle of a sex scene before the guy was supposed to cum she pushed him out of her pussy and forced him on his back. Getting into a mounting position she started sucking on his cock which was super wet from being inside her pussy. She licked all the pussy juice off his dick and sucked him off so hard until he blew. Instead of having him cum on her face she swallowed it making every man in the room wishing they were him.
