La Mesnie Herlequin is a French early music ensemble specializing in medieval and Renaissance repertoire. Originating in France, the group focuses on historically informed performance of vocal and instrumental music from the Middle Ages and early Renaissance, often using period instruments and performance practices to recreate the timbres and textures of those eras. Their repertoire typically includes secular and sacred songs, dance music, and polyphonic pieces, presented with attention to historical sources and scholarship. Active from the late 20th century into the 21st, La Mesnie Herlequin is noted for interpretive clarity and a repertoire rooted in Western European medieval traditions.
