Named after Coteaux-Beauclair, a district of Rosny-sous-Bois.
The district lies below the Boissière neighbourhood, and the station is also to serve the new Coteaux-Beauclair development zone (ZAC). During planning the station was called Londeau-Domus; it serves the Londeau neighbourhood of Noisy-le-Sec and the Domus shopping centre. We have not yet found where the name Beauclair comes from.
