Gilles (died before 1193), Count of Montaigu and Clermont, Count of Duras, son of Godefroi, Count of Montaigu, and his wife Julienne, daughter of Otto II, Count of Duras. Gilles was also Seigneur of Rochefort, Seigneur of Jodoigne and Avoué of Saint-Trond.
In 1174, Gilles married Laurette de Looz, daughter of Louis I, Count of Looz, and his wife Agnes von Metz. They divorced childless in 1176.
Gilles was succeeded as Count of Montaigu, Clermont and Duras by his brother Conon, possibly as early as 1175. In a charter dated 1175 donating property to the Knights Hospitaller, Gilles is referred to as former count and his brothers Pierre and Conon as Counts of Montaigu and Duras, respectively.
