The Panthéon (Latin Pantheon, from Greek Pantheon, meaning "Every god") is a building in the Latin Quarter in Paris, France. It was originally built as a church dedicated to St. Genevieve, but after many changes now combines liturgical functions with its role as a famous burial place.

It is an early example of Neoclassicism, with a façade modelled on the Pantheon in Rome, surmounted by a dome that owes some of its character to Bramante's "Tempietto". Located in the 5th arrondissement on the Montagne Sainte-Geneviève, the Panthéon looks out over all of Paris.

Its architect, Jacques-Germain Soufflot, had the intention of combining the lightness and brightness of the gothic cathedral with classical principles. Soufflot died before his work was achieved, and his plans were not entirely followed. The transparency he had planned for his masterpiece was not attained. Nevertheless, it is one of the most important architectural achievements of its time and the first great neoclassical monument.
