Khalifa Halima St. Fort (born 13 February 1998) is a track and field sprinter who competes internationally for Trinidad and Tobago.

While at high school she struggled to improve her sprinting and her father contacted Ato Boldon, a four-time Olympic medalist for Trinidad and Tobago, for assistance.

Boldon decided to coach St. Fort and after a month she improved her best from 12.3 to 11.5 seconds, making her one of the top ranked sprinters for her age group globally.

[3] St. Fort produced three personal bests at the competition, running 11.39, 11.24, then 11.19 seconds in the final to secure the silver medal behind Hill.

In the final, she was replaced by Semoy Hackett and the team improved the record further in their bronze medal-winning run.
