"A New Day" is a single by English post-punk band Killing Joke.

The B-side to the 7" release was a remix of the song, named "Dance Day".

Muriel Gray at Smash Hits said, "A very dated guitar riff announces the fact that we're not to expect anything new from Killing Joke in this latest release.

They're apparently attempting to sound threatening and raw, but the band have always been a little bit guilty of being pantomime punks, and this just reinforces that pastiche.

The 12" single featured a dub mix of "A New Day" as its A-side and the original track as the B-side.
