Sink is a Foetus Inc compilation album that was first released in 1989 on Self Immolation/Some Bizzare.

It compiles rare and unreleased songs from various Foetus projects from 1981–1989.

Many of the rare tracks on the album have been edited shorter than their original length.

Sink is Foetus' final Some Bizzare record and it was released in 1995 thanks to Some Bizzare Label Thirsty Ear's effort to reissue the Foetus catalogue.

All versions' liner notes contain an up-to-date Foetus discography.
