Guy Le Querrec (born 1941 in Paris, France) is a French photographer and filmmaker, noted for his documentary images of jazz musicians. He is a member of Magnum Photos.
Le Querrec took his first photographs as a teenager using a basic Fex/Indo Ultra-Fex, buying second hand soon after an other and more sophisticated bakelite 6 x 9 cm Photax camera, in 1955. He shot his first pictures of jazz musicians in London in the late 1950s. After having served in the army, he became a professional in 1967, and then worked as a picture editor and photographer for Jeune Afrique magazine, working in francophone Africa, including Chad, Cameroon, Niger, and Central African Republic. In 1971 he gave his archives to Agence Vu, founded by Pierre de Fenoyl and then co-founded Viva (photo agency). In 1976, he left Viva and joined Magnum Photos.
In the late 1970s he began directing films, working with Robert Bober. In 1983 at the Rencontres d'Arles he experimented with projecting images while a jazz quartet played.
Besides having photographed numerous jazz festivals and African subjects, Le Querrec has traveled to China and documented American Indians. He has documented Villejuif, a suburb of Paris, as well as the Carnation Revolution in Portugal. He has also taught many photography workshops in France.
