Mark of the Mole is the eighth studio album by American art rock group The Residents, released in 1981 on Ralph Records.

The first in what was intended to be a "trilogy" (of six albums) with a narrative centred on a conflict between two rival peoples, the Moles and the Chubs.

The Moles enter the land of the Chubs (a vapid, hedonistic culture which resides under the sea), seeking work and a new home.

Conflict arises when a Chub scientist invents a machine that can do the work instead, making the Moles obsolete and sparking a brief war.

ends the album without giving a clear conclusion to the narrative; the liner notes to the album The Big Bubble (billed as "Part Four of the Mole Trilogy") states that the war ended with no clear winner, and the two ethnic groups live together in uneasy peace into the next generation.
