Église Saint-Lubin-et-Saint-Jean-Baptiste de Rambouillet, Neo-Gothic church in Rambouillet, France

The Église Saint-Lubin-et-Saint-Jean-Baptiste is a Neo-Gothic church in Rambouillet with a Latin cross layout, three vessels, and cast iron columns supporting transverse arches. A bell tower marks the entrance and defines the building's external appearance.

The church was built between 1868 and 1871 after architect Anatole de Baudot won a municipal competition. The project received financial support from Napoleon III and became part of Rambouillet's urban development during that period.

The church is dedicated to Saint Lubin of Chartres, the town's patron saint, and to John the Baptist. In 1870 the Ministry of Fine Arts commissioned sculptors François-Antoine Zoegger and Louis-Gustave Gaudran to carve two stone statues of musical angels, later placed behind the choir.

The church stands on Place Jeanne d'Arc, reached by the rue Napoléon laid out for it in 1867–1868. The building is inscribed as a monument historique since 2003. The main entrance is the arched portal at the base of the bell tower, and the nave and side aisles are fitted with light wooden chairs rather than fixed pews.

The church honours Lubin of Chartres, the town's patron saint, alongside John the Baptist. Its construction was paid for by three separate purses: 100,000 francs from Emperor Napoleon III's personal treasury, 100,000 francs from the Ministry of Cults, and 200,000 francs borrowed by the municipality. The first stone was laid on 14 April 1868.
