Charles Voirin, called Varin, (20 January 1798 (1er pluviôse an VI) [1] – 24 April 1869) was a 19th-century French playwright.

Destined by his father to the profession of notary, Varin spent ten years at the bottom of a study, where he once came to Paris without money.

Interested in writing plays, he spent a long time to break the circle of obstacles which opposed its inception.

When the first success came, around 1825, he called himself Victor first, then took the pseudonym Varin, so that his father kept in ignorance of its gains, would not suppress his student pension.

To cite only a few: Bayard, Clairville, Desvergers, Paul de Kock, Duvert, Labiche, Auguste Lefranc, Henri Rochefort, Étienne and Jacques Arago.
