The Boulevard Saint-Michel (French pronunciation: [bulvaʁ sɛ̃ miʃɛl]) is one of the two major streets in the Latin Quarter of Paris, France, the other being the Boulevard Saint-Germain. It is a tree-lined boulevard which runs south from the Pont Saint-Michel on the Seine and Place Saint-Michel, crosses the Boulevard Saint-Germain and continues alongside the Sorbonne and the Jardin du Luxembourg, ending at the Place Camille Jullian just before the Port-Royal RER station and the Avenue de l'Observatoire. It was created by Baron Haussmann to run parallel to the Rue Saint-Jacques which marks the historical north-south axis of Paris. It is known colloquially as Boul'Mich' in French.
The boulevard serves as a boundary between the 5th and 6th arrondissements of Paris; odd-numbered buildings on the eastern side are in the 5th arrondissement and even numbers on the western side are in the 6th. It has a length of 1,380 m (4,530 ft), an average width of 30 m (98 ft) and takes its name from the Pont Saint-Michel.
