The rue de la Harpe is a street in Paris' Latin Quarter. Relatively calm and cobblestoned along much of its length, it runs in a south-easterly direction between the rue de la Huchette and the rue Saint-Séverin, where it turns south-west to where it ends at the boulevard Saint-Germain. It is a largely residential street; it is graced through its odd numbers (eastern side) with a few buildings dating from the Louis XV period, but buildings along the opposite side of the street are most all of a 'Haussmannian' style of a more recent stature. Its street-front commerces are varied to its southern end, but tend towards restaurants and the tourism trade towards the river.
