The Tour Saint-Jacques (, 'Saint James's Tower') is a monument located in the 4th arrondissement of Paris, France, at the intersection of Rue de Rivoli with Rue Nicolas Flamel. This Flamboyant Gothic tower is all that remains of the former 16th-century Church of Saint-Jacques-de-la-Boucherie ("Saint James of the butchers"), which was demolished in 1797, during the French Revolution, leaving only the tower.
