Simon Jonathon Gallup (born 1 June 1960 in Duxhurst, Surrey) is an English musician and bassist of the post-punk band The Cure. Gallup first joined The Cure in 1979, replacing Michael Dempsey on bass guitar. He also has been credited for occasionally playing the keyboard, particularly after Matthieu Hartley's departure in 1980; he took over keyboard lines for many of the songs that Hartley played. Examples of songs he played keyboard on live include "At Night", A Forest, "A Strange Day" and Pornography. During Cold he multi-tasked playing bass guitar and bass pedals. On the Swing Tour in 1996, he played acoustic 12-string guitar on "This is a Lie".
