Project: Mersh is the final extended play by American punk rock trio Minutemen, released on April 8, 1985 through SST Records.

It is the band's penultimate release before the death of frontman and composer D. Boon later that year due to injuries sustained in an auto accident.

All six songs surpass the two-minute mark ("More Spiel" is nearly six minutes long) and incorporate verses, choruses, hooks, and fade outs,[8] in contrast to nearly all the band's previous recordings.

Crane, who provided backing vocals and played the trumpet on Buzz or Howl Under the Influence of Heat, returned to lend his voice and instrumentals to the album.

"[10] Byron Coley at Spin said "it seemed a forward-moving continuation of the form annihilation the band had undertaken with Double Nickels on the Dime.
