Raimbaut de Vaqueiras or Vaqueyras (fl. 1180 – 1207) was a Provençal troubadour and, later in his life, knight. His life was spent mainly in Italian courts until 1203, when he joined the Fourth Crusade. Raimbaut's works include a multilingual poem, Eras quan vey verdeyar where he used French, Italian, Galician-Portuguese and Gascon, together with his own Provençal.
