Pierre Clereau (died before 11 January 1570) was a French composer, choirmaster and possibly organist of the Renaissance, active in several towns in Lorraine, including Toul and Nancy.
In 1554, he was in Toul working as a choirmaster, as stated on the title page of two volumes of sacred music published by Parisian Nicolas Du Chemin.
René, Marquis of Elbeuf, was a patron and supporter of Clereau, and assisted in the publication of his work by the prestigious, and monopolistic, royal printers of Le Roy & Ballard in Paris.
These works are all parody masses, and are based on motets by Pierre Certon, Thomas Crecquillon and Jean Maillard.
His other sacred music, particularly the Cantiques spirituels, shows the influence of the Huguenots, the French Protestant composers of the 16th century, with their simple homophonic textures and melodic line in the topmost voice; in addition, one of them uses a tune taken from the Genevan Psalter, an extremely unusual thing for a Roman Catholic composer to do during the Wars of Religion.
