Théâtre Graslin is a theatre and opera house in the city of Nantes, France, built in a new district of the city in the late 18th century by the local architect Mathurin Crucy, and named after the owner of the land, Jean-Louis Graslin. Constructed in the Italian style, the auditorium holds 823 people.
Inaugurated on 23 March 1788, it quickly became a major opera house for the city which nowadays, along with the Grand Théâtre d'Angers, combines with Angers to form a joint Angers-Nantes opera.
Théâtre Graslin was destroyed by fire 1796, but it was reconstructed to coincide with the 1811 visit by Emperor Napoleon.
