Louise Dimanche (before 1715 - floruit 1739), was a French actress, opera singer, ballet dancer, and theatre director.
Dimanche was a dancer at La Monnaie in 1715, where she took part in Les Nouvelles Fêtes vénitiennes by Antoine Danchet and André Campra.
It was followed by a performance of Omphale by Antoine Houdar de La Motte and André-Cardinal Destouches.
Afterwards, she danced and sang in Lille in 1715–1718, where she married her first husband Antoine Vernet, a singer also known as Forêt.
After a short stay in The Hague in 1719, Dimanche was appointed director of Théâtre Royal de la Monnaie in Brussels.
