Named after the Gare Saint-Lazare and the rue Saint-Lazare.
The street has had its name since 1770: it led to the maison Saint-Lazare, a leper hospital mentioned as early as 1110 under Saint Lazarus, patron of lepers in the Middle Ages, which became a prison in 1793. Before that the street was the rue des Porcherons, then the rue d'Argenteuil, after the village it led towards. The station serves the gare Saint-Lazare, built in 1837.
