Tiffany Jane Cromwell (born 6 July 1988) is an Australian road and gravel cyclist, who currently rides for UCI Women's WorldTeam Canyon–SRAM zondacrypto.

[3] Starting in 2002, after being identified by the South Australian sports institute talent identification program, Cromwell began her cycling career.

[4] Initially, Cromwell disliked cycling, citing that she was 'Tiny and one of the worst in [her] group' on the track, but soon discovered her love for the sport when she placed third in her first road race in the state championships.

[5] After several podiums in junior Oceania games, one of Cromwell's first international wins came in 2008 at the Sea Otter Classic in California, having made a solo attack in the last few laps despite a 30 miles per hour (48 km/h) wind.

[11] She recorded several stage podiums in the 2014 Tour Cycliste Féminin International de l'Ardèche and finished second in the mountains classification.

Cromwell represented Australia at the Commonwealth Games,[12] losing out on a bronze medal in the road race in a two-up sprint with South Africa's Ashleigh Moolman.

[17] In 2018, Cromwell was again selected to represent Australia at the Commonwealth Games,[18] where, as road captain, she was part of the team that supported Chloe Hosking to the gold medal.

[21] On 27 October 2021, it was announced Cromwell would remain as part of the Canyon-SRAM team for a further two years, continuing her mixed program of road and gravel racing through until the end of 2023.
