Tanya Bailey (born 15 March 1981, in Dampier, Western Australia) is an Australian amateur BMX cyclist.

In that same year, Bailey has also achieved ample success in the sport, finishing second at the Australian national championships and the Supercross World Cup, held in Adelaide, South Australia.

[2] Throughout her sporting career, Bailey has been training with her personal and assistant national coach Wade Bootes for the Wanneroo BMX Club in Gold Coast, Queensland.

[3] Along with her teammate Nicole Callisto, Bailey qualified for the Australian squad in women's BMX cycling at the 2008 Summer Olympics in Beijing by receiving one of the nation's two available berths from the Union Cycliste Internationale, based on her best performance at the UCI World Championships in Taiyuan, China.

9 in the UCI rankings for female BMX cyclists and grabbed a tenth seed on the morning prelims with a time of 38.285, Bailey could not match a stellar ride in her semifinal heat with two unfulfilled attempts, a total of 22 positioning points, and an eighth-place finish, thus eliminating her from the tournament.
