Robert Jules Guédiguian (born 3 December 1953) is a French filmmaker, producer and actor. Most known for Marius and Jeannette (1997) and Gloria Mundi (2019), his films usually star his wife Ariane Ascaride or Jean-Pierre Darroussin.

Guédiguian is the son of a German mother and an Armenian father, whose family immigrated to France in the early 20th century after the Armenian genocide. He evokes his paternal roots in his 2006 film Le Voyage en Armenie. He has a working-class background, as his father is a worker on the Marseille docks. Guédiguian became concerned with political questions and for a while was involved with the French Communist Party. In 2008 he joined the Left Party in France.
