Pierre Renoir (French pronunciation: [pjɛʁ ʁənwaʁ]; March 21, 1885 – March 11, 1952) was a French stage and film actor.

He is also noted for being the first actor to play Georges Simenon's character Inspector Jules Maigret in Night at the Crossroads, directed by his brother.

Pierre Renoir was born on March 21, 1885, in Paris, at 18 rue Houdon, about a hundred meters from place Pigalle, to painter Pierre-Auguste Renoir and Aline Charigot.

For his best remembered role, as Jėricho the ragman in Children of Paradise (Les Enfants du Paradis, 1945), he was cast at short notice to replace the collaborator Robert Le Vigan; Jėricho's scenes had to be reshot after Le Vigan fled.

Renoir was briefly the director of the Théâtre de l'Athénée in Paris, taking over after the death of Louis Jouvet in 1951.
