Kelsey Marie Mitchell (born 26 November 1993) is a Canadian professional track cyclist, most proficient in the sprint event.

"[1] She participated in RBC Training Ground, an athlete funding and talent identification program, which steered her into track cycling.

[6] Mitchell's individual and team results in Cochabamba qualified her to make her World Championship debut at the 2020 edition in Berlin.

[7] Mitchell's results were intended as a ramp-up to the 2020 Summer Olympics in Tokyo, but shortly after the 2020 World Championships, the entire cycling calendar was disrupted by the onset of the COVID-19 pandemic.

Mitchell's training was relatively unaffected by the pandemic, as she and her teammates were able to continue on in Milton, Ontario, but they were unable to compete at any leadup events.

After placing fifth in the keirin, Mitchell won the gold medal in the sprint on the final day of the Tokyo Games, best silver medallist Olena Starikova by two laps to zero.

[13] Mitchell finished the season on the newly established UCI Track Champions League circuit, coming third overall across the four sprint events.

[18] The following day, Mitchell won a second silver medal in the sprint, losing in the final to New Zealander Ellesse Andrews.
