Chrétien de Troyes was a French poet and trouvère known for his writing on Arthurian subjects such as Gawain, Lancelot, Perceval and the Holy Grail. Chrétien's chivalric romances, including Erec and Enide, Lancelot, Perceval and Yvain, represent some of the best-regarded works of medieval literature. His use of structure, particularly in Yvain, has been seen as a step towards the modern novel.

Trouvère, sometimes spelled trouveur, is the Northern French form of the langue d'oc (Occitan) word trobador, the precursor of the modern French word troubadour. Trouvère refers to poet-composers who were roughly contemporary with and influenced by the trobadors, both composing and performing lyric poetry during the High Middle Ages, but while the trobadors composed and performed in Old Occitan, the trouvères used the northern dialects of France. One of the first known trouvère was Chrétien de Troyes and the trouvères continued to flourish until about 1300. Some 2130 trouvère poems have survived; of these, at least two-thirds have melodies.
