Chelles (French pronunciation: [ʃɛl] ⓘ) is a commune in the eastern suburbs of Paris, France.

It is located in the Seine-et-Marne department in the Île-de-France region 18 km (11 mi) from the center of Paris.

Paleolithic artifacts were discovered by chance at Chelles by the pioneering nineteenth-century anthropologist Louis Laurent Gabriel de Mortillet (1821–1898); he named the corresponding cultural stage of the Paleolithic after the commune: «Chellean» or «Chellian», nowadays known as «Oldowan».

At the Merovingian villa of Calae the abbey of Notre-Dame-des-Chelles was founded by Balthild, a seventh-century queen of the Franks.
