El Ten Eleven is an American post-rock duo based out of Los Angeles, California. They are known for combining guitar/bass doubleneck or fretless bass, with heavy looping, or vamping, and the use of an effects pedal, over acoustic or electric drumming. They have released ten full-length albums, 2 EPs and a remix album, earning generally positive reviews.

The band has earned some attention due to many of their songs being featured in the soundtracks of Gary Hustwit's design documentaries Helvetica, Objectified, and Urbanized.

The name El Ten Eleven is derived from the name of an airliner, the Lockheed L-1011 TriStar.
