Gautier Serre (born June 5, 1984), better known by his stage name Igorrr, is a French musician. Under the Igorrr alias, he combines a variety of disparate genres, including black metal, baroque music, breakcore, and trip hop, into a singular sound. Serre is also part of the groups Whourkr and Corpo-Mente. The Igorrr project became a full band with the addition of vocalists Aphrodite Patoulidou and JB Le Bail, plus the drummer Sylvain Bouvier and the guitarist Martyn Clément.
