Named after Les Agnettes, the locality where it stands.
The station lies on the border of Asnières-sur-Seine and Gennevilliers, and its subtitle names both towns. Les Agnettes is also a quarter of Gennevilliers, which gave its name to the church Notre-Dame-des-Agnettes; another source points instead to the nearby rue des Agnettes. We have not yet found out what the name Agnettes means.
