Saint-Pierre (English: Saint Peter) is a concrete building in the commune of Firminy, France.

Designed to be a church in the model city of Firminy Vert, the construction of Saint-Pierre was begun in 1971, six years after Le Corbusier's death in 1965.

The building was completed by the French architect José Oubrerie, Le Corbusier's student for many years.

As the secularist French state may not use public funds for religious buildings, Saint-Pierre is now used as a cultural venue.

American deconstructionist architect Peter Eisenman asserted in his response that this building is the most important structure built since 1980.
