Robert Gravel (14 September 1944 – 12 August 1996) was an actor, dramatist, theatrical director and teacher.
Gravel was born in Montreal. He was an influential figure in the modern history of theatre in Quebec. In the middle of the 1970s, Gravel, Jean-Pierre Ronfard and Pol Pelletier co-founded the Théâtre Expérimental de Montréal (TEM). Later ideological conflicts led to the foundation of the Nouveau Théâtre Expérimental.
In 1977, Gravel co-founded with Yvon Leduc the highly successful Ligue Nationale d'Improvisation. He died in Saint-Gabriel-de-Brandon in 1996 and was entombed at the Notre Dame des Neiges Cemetery in Montreal.
