Lost to Apathy is the fifth EP by Swedish melodic death metal band Dark Tranquillity.

The album also includes the video for "Lost to Apathy", produced by Roger Johansson (who worked with other bands such as The Haunted, In Flames, and HammerFall) and a Dark Tranquillity screensaver.

"Derivation TNB" is a joint remix of some clean riffs from "The New Build", "Mind Matters" and "Dry Run", songs from Character.

A shorter version (only the "New Build" riff) can be found at the end of "Through Smudged Lenses", also in the Character album.

The EP also includes an industrial remix of "The Endless Feed".
