Named after the rue Saint-Sébastien and the rue Froissart.
The rue Saint-Sébastien took its name from a shop sign honouring the Roman martyr Saint Sebastian. The rue Froissart honours Jean Froissart (about 1337–1400), one of the great chroniclers of the Middle Ages. The station opened in 1931 as Saint-Sébastien and took its present name in 1932.
