Guillaume le Heurteur (also found under the form Guillaume Heurteur and Guillaume Hurteur) was a French composer of the Renaissance about whom very little is known.
Also a canon and preceptor of the choirboys of the Collegiate church Basilica of Saint Martin, Tours as evidenced by the title page of a collection of motets published in the same year, Le Heurteur was the author of four masses, two Magnificats, twenty-one motets and twenty-three songs, published between 1530 and 1549, mainly by Pierre Attaingnant, printer in Paris.
Very little information is available on Guillaume le Heurteur. His name is quoted by François Rabelais in the second prologue to the , published in 1552, alongside those of Josquin des Prés, Pierre de La Rue and Jean Mouton.
