thumb|right|Cercamon in a 13th-century chansonnier. Cercamon (, fl. 1135-1145) was one of the earliest troubadours. His true name and other biographical data are unknown. He was apparently a Gascony-born jester of sorts who spent most of his career in the courts of William X of Aquitaine and perhaps of Eble III of Ventadorn. He was the inventor of the planh (the Provençal dirge), of the tenso (a sort of rhymed debate in which two poets write one stanza each) and perhaps of the sirventes.
