The Mothers 1971 is a box set by Frank Zappa, released posthumously on March 18, 2022.

It is a compilation of live music mainly consisting of several shows recorded at the Fillmore East which were originally intended for album Fillmore East – June 1971, including an encore with guest musicians John Lennon and Yoko Ono, which had been previously released on the CD Playground Psychotics.

The box set also includes a 'hybrid show' recorded in Harrisburg and Scranton, Pennsylvania, on June 3, and June 1, respectively, as well as a homemade radio spot, a single version of the song "Tears Began To Fall" (along with its B-Side), and lastly, a recording from the Rainbow Theatre in London, England, on December 10.

[1] This would be the final show the band would play in 1971, as it concluded with Frank Zappa being pushed off the stage by an audience member, causing life-altering injuries, a months-long hiatus from performing live, and thus putting an end to the tour and this era of Zappa's career.
