The Rue Saint-Lazare is a street in the 8th and 9th arrondissements of Paris, France. It starts at 9 Rue Bourdaloue and 1 Rue Notre-Dame-de-Lorette, and ends at the Place Gabriel-Péri and the Rue de Rome.

This street already existed in 1700 under the name of Rue des Porcherons or Rue d'Argenteuil, and connected the villages of Roule and Ville-L’Évêque to the village of Porcherons. In 1734, it was still only lined with few buildings. The present name dates from 1770 and comes from the Maison Saint-Lazare toward which it led (via the rues Lamartine, Bleue, and Paradis) and which had been used as a leprosarium since the Middle Ages; it was converted into Saint-Lazare Prison in 1793. It stood at the current location of no. 117 rue du Faubourg-Saint-Denis, in the 10th arrondissement.

A ministerial decision of 12 Fructidor V (29 August 1797) set the minimum width of the street at 10 metres (33 ft). This width was increased to 11 metres (36 ft) by a royal decree of 3 August 1838. An order of 3 September 1843 declared the public utility of expansion to 20 metres (66 ft) to the right of the properties at nos. 115–121 to create the Cour du Havre.

The Gare Saint-Lazare was built in 1837. An alley, the Impasse Bony, created in 1826 and located at the site of the Hotel Terminus, was used for unloading luggage. The Cour de Rome, in front of the station on the west side, encompassed the old Impasse d’Argenteuil, which opened onto the Rue du Rocher.

• Nos. 27–29 (and nos. 32–34, Rue de Châteaudun): Two notable buildings, decorated in the style of 16th-century French architecture, built around 1840. Probably one of the most important collections of this style. The rear facades are visible from the Rue de Châteaudun, whose extension in 1862 appears to have cut these buildings off from their garden.
