Jehan Erart (or Erars) (c.1200/10–1258/9) was a trouvère from Arras, particularly noted for his favouring the pastourelle genre.
In his serventois, a complainte on the death his patron Gherart Aniel, he asked Pierre and Wagon Wion to help him obtain the patronage of the bankers Henri and Robert Crespin.
His relationship with two Arras trouvères is apparent in his lyrics, Guillaume le Vinier and Jehan Bretel.
The chief characteristic of Erart's poetry is his preference for short lines, mostly penta-, hexa-, hepta-, and octosyllabic, as opposed to the traditional decasyllable, which does occur in his chansons "Pré ne vergier ne boscaige foillu" and "Encoire sui cil ki a merchi s'atent" and his serventois "Nus chanters".
[1] Three songs attributed to Jehan Erart in one manuscript probably belong to Raoul de Beauvais.
