Theresa Goh Rui Si BBM (simplified Chinese: 吴蕊思; traditional Chinese: 吳蕊思; pinyin: Wú Ruǐ Sī; born 16 February 1987) is a Singaporean swimmer and Paralympic medalist, with a bronze at the SB4 100m breaststroke at the 2016 Summer Paralympics.

At the 4th ASEAN ParaGames held in Nakhon Ratchasima (Korat), Thailand, in January 2008, Goh broke the record she set in May 2007 at the German International Disability Swimming Championships to win the gold in the 50 metres breaststroke in a world and FESPIC record time of 52.62 seconds.

In the same year, she was presented the Bintang Bakti Masyarakat (Public Service Star) in the National Day Awards.

They were also shocked to discover that she had congenital spina bifida, which results in an incompletely formed spinal cord, as the condition had not been detected during her mother's pregnancy.

[9] She soon established herself as a top competitor, achieving a run of four gold medals at the 10th Malaysian Paralympic Games and ASEAN Invitation Championships in 2000.

At the inaugural ASEAN Para Games in Kuala Lumpur in 2001, she garnered six gold and two silver medals, and broke the world record in the 50 metres breaststroke.

[23] Despite not training intensively for the 4th ASEAN ParaGames held in Nakhon Ratchasima (Korat), Thailand, between 20 and 26 January 2008, and regarding the competition as part of her training for the 2008 Summer Paralympics in Beijing in September, Goh broke the record she set in May 2007 at the German International Disability Swimming Championships to win the gold in the 50 metres breaststroke in a world and FESPIC record time of 52.62 seconds.

[30] Her current training schedule involves two-hour sessions at the Farrer Park Swimming Complex twice a day, except on Wednesday mornings and Sundays, which works out to about 42 kilometres (26 mi) a week.

[27] Two days later she narrowly missed a bronze in the 200 metres freestyle, finishing fourth with a new personal best time and national record of 3 minutes 14.22 seconds.

[28][33] According to her coach, former Olympian Ang Peng Siong, her best chance of a medal lay in the 100 metres breaststroke.

Her personal best time for this event is 1 minute 58.14 seconds, which she achieved in May 2007 at the International German Championships in Berlin.

[36] In the 2016 Summer Paralympics, Goh won a bronze medal in the SB4 100m breaststroke final, with a time of 1 minute and 55.55 seconds.
