The Institut de France (French for 'Institute of France'; French: [ɛ̃stity də fʁɑ̃s]) is a French learned society, grouping five académies, including the Académie Française. It was established in 1795 at the direction of the National Convention. Located on the Quai de Conti in the 6th arrondissement of Paris, the institute manages approximately 1,000 foundations, as well as museums and châteaux open for visit. It also awards prizes and subsidies, which amounted to a total of over €27 million per year in 2017. Most of these prizes are awarded by the institute on the recommendation of the académies.

The building was originally constructed as the Collège des Quatre-Nations by Cardinal Mazarin, as a school for students from new provinces attached to France under Louis XIV. The inscription over the façade reads "JUL. MAZARIN S.R.E. CARD BASILICAM ET GYMNAS F.C.A M.D.C.LXI", attesting that Mazarin ordered its construction in 1661.

The Institut de France was established on 25 October 1795, by the National Convention.

On 1 January 2018, Xavier Darcos took office as the Institut de France's chancellor. Elected in 2017 to succeed Gabriel de Broglie, he was reelected in 2020. The chancellor acts as the institute's secretary general, whilst the organisation itself is placed under the protection of the president of the republic.
