Mur Murs ([myʁ myʁ], French for "wall walls", also punning on English "murmurs") is a 1981 documentary film directed by Agnès Varda.

The film explores the murals of Los Angeles, California.

The film alternates between voiceover narration by Agnès Varda and commentary about the murals provided by the murals' creators, as well as commentary provided by locals living in the area.

A significant amount of the film's attention is focused on work by Chicano artists, although artists from other backgrounds are also covered extensively.
