1983–1991

1983–1991 is a four-CD box set of material by gothic rock supergroup This Mortal Coil, released in 1993 on the 4AD label. The box set was released only in the United States, and was distributed by Warner Bros. Records, with whom 4AD maintained a distribution deal at the time. This marked the first domestic USA release for most of the band's output, as only the debut, It'll End in Tears, had been released in the USA previously.

The box set contains all three of the band's LPs, presented in their original form, with no bonus tracks or extra material. The fourth CD is entitled "Original Versions," and features the original recordings of 21 of the many songs the band covered.

Featuring lavish packaging typical of 4AD and design associates V23, the box set has been out of print for many years

The box set is dedicated to His Name Is Alive frontman Warren Defever.
