"Los Endos" is an instrumental piece by English progressive rock band Genesis from their 1976 album A Trick of the Tail. It is one of the band's few forays into the world of jazz fusion and reflects drummer Phil Collins's involvement in the instrumental band Brand X. As the title suggests, the song was featured at the end of the album, and it was also featured at the end of Genesis's concerts, usually as a medley with "Dance On A Volcano" and a drum duet between Collins and Chester Thompson in between.

The song contains excerpts from three other songs recorded during the Trick of the Tail sessions: The intro is from "It's Yourself," a song which appeared as the B-side to "Ripples" (as well as "Your Own Special Way" from the Wind & Wuthering album in 1977.) The closing section features riffs and melodies from "Dance On A Volcano" and "Squonk".

During the fade out of the song, Phil Collins sings "There's an angel standing in the sun...There's an angel standing in the sun / free to get back home." These lines are from the "As Sure As Eggs is Eggs (Aching Men's Feet)" section of "Supper's Ready" from 1972's Foxtrot. The band included these lyrics in "Los Endos" as an homage to original lead vocalist Peter Gabriel, who had left the band in 1975.

The reprise of "Dance on a Volcano" at the end of "Los Endos" gives the album a bookend effect that is found on other Genesis albums, such as Selling England by the Pound, Seconds Out and Duke.

A live version of "Los Endos" appears on Genesis: In Concert, Seconds Out, the Encore Series recordings of Turn It On Again: The Tour and Live Over Europe 2007. It was also featured on Genesis' 3-disc compilation album Platinum Collection as one of three cuts from A Trick of the Tail (along with "Ripples" and "A Trick of the Tail"), remixed by Nick Davis.
