Temple du Luxembourg, Protestant church in 6th arrondissement of Paris, France.

The Temple du Luxembourg stands at 58 rue Madame in the 6th arrondissement, its light tan ashlar facade continuing the line of neighbouring buildings. Three tall arched windows with diamond-patterned leaded glass and stone mullions sit above a pointed-arch doorway framed in rusticated stone; a ball-flower cornice separates them from smaller windows above. The worship hall occupies the first floor, a rectangle of five bays whose pillars carry neo-Gothic capitals carved with vine leaves.

The church opened in 1857 to serve a growing Protestant community in Paris seeking its own place of worship. It became an independent parish within a decade, establishing itself as an established religious institution in the neighborhood.

The temple's name comes from the rue Madame address in the 6th arrondissement, near the Luxembourg Gardens; the congregation is now the Église protestante unie de Pentemont-Luxembourg, formed in 2013 by the merger of the Luxembourg and Pentemont parishes. The building is still an active Reformed place of worship.

The worship hall is on the first floor, reached by three simple staircases or a lift installed in the 1989 works, which replaced a large double-revolution staircase. The entrance is at 58 rue Madame, its pointed-arch doorway set between the ground-floor windows; the facade carries no cross, only a gable above the portal.

The worship hall ceiling features a false oculus displaying a Star of David, an unexpected symbol in this Protestant setting. The large windows with their geometric diamond pattern represented modern design thinking when the building was completed in the 1800s.
