Conches-sur-Gondoire (French pronunciation: [kɔ̃ːʃ syʁ ɡɔ̃dwaːʁ] ⓘ) is a commune on the Gondoire river in Brie, in the Seine-et-Marne department in the Île-de-France region in north-central France.

During the middle-ages, Conches-sur-Gondoire consisted of a monastery located on the top of a slope, but during the so-called "Wars of Religion" of the 16th century, the closter and the conventual buildings were destroyed by a troop of Protestant soldiers.

Nowadays remain the church (13th century), a Gothic cellar with column and capital, a square pond faced with stones, tombs and peasant cottages.

In Conches-sur-Gondoire, one of the remaining houses of the monastery belongs to French painter Maurice Boitel, who made numerous pictures in this village during the second half of the 20th century.

During the sixties, his house was the meeting place for many painters, scientists, and musicians, including; Gabriel Deschamps, Pierre Gaillardot, Pierre Dejean, Maurice Faustino-Lafetat, Louis Vuillermoz, Albert Besson, Daniel du Janerand, and Françoise Ardré.
