François-Joseph-Philoclès Regnier de La Brière called Regnier (Paris, 1 April 1807 – Paris 27 April 1885) was a 19th-century French actor and playwright. The comedian Alcide Tousez was his uncle.
After he studied by the Oratorians, he made his comedian debut at the Théâtre Montmartre in 1826 then toured the French provinces, particularly in Metz and Nantes. He was admitted at the Comédie-Française in 1831, became a sociétaire in 1835 then the dean in 1865 before retiring in 1871. In 1884, he also became a professor at the Paris Conservatory, where among his students were Réjane, Marguerite Durand, Jules-Théophile Boucher and Constant Coquelin.
In a letter from 1876 Regnier says that the unusual first name of Philoclès comes from the French translation of Agathocle by Christoph Martin Wieland whose his godfather was a great admirer. The name of Charles was substituted at his baptism, but the destruction of civil registers during the Paris Commune allowed him to recover it at the time of the reconstitution of his birth certificate.
