Marnes-la-Coquette (French pronunciation: [maʁn la kɔkɛt] ⓘ) is a commune in the western suburbs of Paris, France.

Located 13.1 km (8.1 mi) from the centre of Paris, the town is situated in the Hauts-de-Seine department on the departmental border with Yvelines between the Parc de Saint-Cloud and the Forest of Fausses-Reposes.

[3] The small town of Marnes was formed sometime in the late 12th century when the French bishop Eudes de Sully created a village in the middle of a forest that belonged to him.

A portion of the area of Marnes-la-Coquette was granted to Louis Pasteur in order for him to continue his research after his discovery of the vaccine against rabies in 1885.

The experiments required many rabbits and dogs to be caged, which became too much of a nuisance for the neighborhood around Pasteur's animal-house on Rue d'Ulm (5th arrondissement) in Paris.
