Nicholas Rees (born February 17, 1982) is a Bahamian former swimmer, who specialized in butterfly events.

Rees made his first Bahamian team, as an eighteen-year-old junior, at the 2000 Summer Olympics in Sydney, where he competed in the men's 100 m butterfly.

Swimming in heat two, and struggling with a crippling shoulder injury, he rounded out a field of eight swimmers to fifty-seventh overall by 0.77 of a second behind Bermuda's Stephen Fahy in 57.23.

[3][4] At the 2004 Summer Olympics in Athens, Rees qualified again for the 100 m butterfly, by clearing a FINA B-standard entry time of 55.89 from the World Championships in Barcelona, Spain.

[2][5] He challenged seven other swimmers on the second heat, including fellow two-time Olympians Conrad Francis of Sri Lanka and Daniel O'Keeffe of Guam.
