The Porte du Peyrou is a triumphal arch in Montpellier, in southern France.
It is situated at the eastern end of the Jardin de Peyrou, a park near the center of the city.
The arch was designed by François Dorbay, after the model of the Porte Saint-Denis in Paris.
Its later panels in bas-relief and inscriptions glorifying King Louis XIV of France were added in 1715.
These reliefs show four major events from the reign of Louis XIV, rendered as allegories: Montpellier as seen from the Porte du Peyrou.
