Derek Forbes (born 22 June 1956, Glasgow, Scotland) was the Scottish bassist for Simple Minds, from the album, Life in a Day, through to their hit, "Don't You (Forget About Me)".
His departure from the band was due to stylistic musical differences with the rest of the band during the recording of "Don't You (Forget About Me)" and prior to the release of Once Upon a Time. Forbes reunited with the band briefly during the recording of Néapolis, but he only recorded bass lines for the song "War Baby". Forbes quit the band once more after touring for Néapolis, again citing his differences with the band and their musical direction.
Forbes started his musical career in the U.K. Subs. He contributed to their singles, "Gimme Your Heart" and "Party in Paris".
After Simple Minds, Forbes went on to play in number of other bands, including Propaganda and Oblivion Dust. He currently he plays in Fourgoodmen, a Scottish new wave covers band.
