Tell Me When" is a song by English synth-pop band the Human League, released in December 1994 by East West Records as the first single from their seventh album, Octopus (1995). Music Week rated the single five out of five, describing it as "pristine synth pop as a deep Oakey lead and girl harmonies make this the most joyful single of the week.

As it was the first commercial release in the UK by the band for four years it is often incorrectly described as a comeback as many people erroneously believed the band had disbanded in 1990. Dave Thompson of AllMusic said it echoes earlier material, likening it to " Fascination" and " Mirror Man".

He went further, saying that "the real difference is found in the vignette-esque lyrics and the more complex vocals. Released in a variety of vinyl and CD single formats, these variously included remixes of "Tell Me When" by contemporary electronic acts Utah Saints, Development Corporation and Red Jerry, a non-album B-side ("The Bus to Crookes"), and a track from the band's recent collaboration with Yellow Magic Orchestra.
