Montsinéry-Tonnegrande (French pronunciation: [mɔ̃sineʁi tɔneɡʁɑ̃d]; often unofficially spelled Montsinéry-Tonnégrande; French Guianese Creole: Mousinéri-Tonnégrann) is a commune of French Guiana, an overseas region and department of France located in South America.

Montsinéry-Tonnegrande is to the south-west of Cayenne. It contains a botanical garden, and various walking trails. Prison of the Annamites, an internment camp for Indochinese prisoners, was located 38 km outside of town, and connected with a railroad. The camp was in operation between 1931 and 1944.

The commune was previously known as Tonnegrande-Montsinéry, but on 27 March 1969 the name was officially changed into Montsinéry-Tonnegrande.
