Pantheon may refer to:

• Pantheon (religion), the set of gods belonging to a particular religion, mythology or tradition

The Panthéon (, from Greek πάνθειον (ἱερόν) '(temple) to all the gods') is a building in the Latin Quarter in Paris. It was originally built as a church dedicated to St. Genevieve and to house the reliquary châsse containing her relics but, after many changes, now functions as a secular mausoleum containing the remains of distinguished French citizens. It is an early example of neoclassicism, with a façade modeled 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. Designer Jacques-Germain Soufflot had the intention of combining the lightness and brightness of the Gothic cathedral with classical principles, but its role as a mausoleum required the great Gothic windows to be blocked.
