Paul Masterson (born Paul Kevin Masterson) is a Northern Irish DJ and record producer, originally from Belfast and now living in London.

Recording as Amen! UK he had a hi-NRG hit with "Passion", released by Deconstruction Records in 1995. Billboard magazine described it as being "underlined by an intangible but apparent reverence for hi-NRG architects, such as the late Patrick Cowley", praising the track's "crazy-catchy chorus" while slightly criticizing the lack of "meaty" lyrics otherwise.
