During the Middle Ages, Cachan was referred to in Medieval Latin texts as Caticantum, later corrupted into Cachentum, Cachant, and then Cachan. Some understand Caticantum as meaning "singing of the cat", "mewing of the cat", but this is not certain. Some others see a connection with the verb "to hunt" (captiare in Vulgar Latin, chacier in Old French).

• Illustration — The Hôtel de Ville Cachan was originally a hamlet within the commune of Arcueil, later renamed Arcueil-Cachan.
