The Church of Saint-Hilaire (French pronunciation: [sɛ̃.t‿i.lɛʁ]) or Saint-Hilaire-du-Mont (French: [sɛ̃.t‿i.lɛʁ dy mɔ̃]) is a ruined 12th-century church in Paris, France, active until the French Revolution.

An original oratory was built on the site in the 11th century. The site is located on Montagne Sainte-Geneviève on a plot that belonged to the canons of Saint-Marcel.^[1]

In 1158, the building was attested as a parish chapel dedicated to Saint Hilary.^[1][2] The small parish had numerous bookshops —up to 14 on Rue Saint-Hilaire [fr] in 1571.^[1]

During the French Revolution, the church was closed in 1790 and the parish was suppressed in 1793. It was sold as a national good in 1796 and demolished in 1807.^[1]

A drawing of the church shows that the bell tower was made of carpentry with no masonry.^[3]

The ruins of the church are located at 2 Rue Valette [fr] and 1bis Rue de Lanneau [fr] in the 5th arrondissement of Paris.^[3][4]

The few remains include a column with a capital and a part of an arch. They can be seen in a small courtyard that can be reached from 1bis Rue de Lanneau near the corner of the Rue Vallette.^[1][4]
