Simon Paul Militis (born 21 September 1977, Jersey) is a male English former competitive swimmer, who specialized in backstroke and individual medley events.

During his sporting career, Militis also trained for the Portsmouth Northsea Swim Club under head coach Chris Nesbitt.

He eclipsed FINA A-standards of 2:00.75 (200 m backstroke) and 4:20.07 (400 m individual medley) from the British Olympic Trials in Sheffield, England.

[7][8] Three days later, in the 200 m backstroke, Militis challenged seven other swimmers in heat six, including his teammate Adam Ruckwood, Australia's top favorite Matt Welsh, and U.S. world record holder Lenny Krayzelburg.

[11] At the 2002 Commonwealth Games in Manchester, England, Militis enjoyed the race by a massive roar of a delightful home crowd, as he wrested a bronze in 2:01.04, handing an entire medal lock for Great Britain with a one–two–three finish.
