Sarah Jane Bainbridge (born 7 October 1982 in Fleetwood, Lancashire) is an English taekwondo practitioner, who competed in the women's welterweight category.

[4] Bainbridge spurred public attention on her senior debut at the 2003 Summer Universiade in Daegu, South Korea, where she shared bronze medals with the Netherlands' Luttikhuis Oude in the women's 67-kg division.

[3][5] At the 2004 Summer Olympics in Athens, Bainbridge qualified for Team GB's taekwondo squad in the women's welterweight class (67 kg).

[6][7] Bainbridge produced a cautious fight against the Netherlands' Charmie Sobers during her opening bout, resulting in a defeat by just a single-point deficit with a narrow record of 6–7.

When Sobers lost the quarterfinal match to her Filipino opponent Mary Antoinette Rivero, Bainbridge denied her chance to compete for Great Britain's first ever Olympic medal in the repechage.
