Saint-Germain-d'Aunay (French pronunciation: [sɛ̃ ʒɛʁmɛ̃ donɛ] ⓘ) is a commune in the Orne department in the Normandy region of France with a population of 144 inhabitants (2018).

A manor was built at the end of the 15th century by Guillaume de Mallevouë, knight and lord of the manors of Saint-Germain and Notre-Dame-d'Aulnay.

The majority of the manor was destroyed by the French Catholic League in 1589 and was replaced by a half-timbered building.

Both villages are shown on the Cassini map of the area.
