Three into One is the first compilation album from the band Ultravox, released in 1979 in the USA and in June 1980 in the UK. The album is a compilation of songs from their first three albums, Ultravox!, Ha!-Ha!-Ha! and Systems of Romance, and therefore concentrates on the earlier incarnation of the band from the 1970s featuring John Foxx, as opposed to the more recognisable 1980s line-up which featured Midge Ure.
