Thibaut de Blaison, Blason, or Blazon (died after March 1229) was a Poitevin nobleman, Crusader, and trouvère from a noble family with lands in Blason and Mirabel. Eleven poems—one contested and one definitely spurious—have been ascribed to Thibaut in the chansonniers. Three further anonymous songs have also been attributed to him by Terence H. Newcombe, his modern editor.
