Floria Gueï (pronounced [flɔʁja ɡe.i]; born 2 May 1990[1]) is a French sprint athlete of Ivorian origin specialising in the 400 metres.

In August 2014 at the European Championships in Zurich Floria Gueï ran one of the most remarkable final legs of a 4 x 400m relay ever seen.

She took the baton in fourth place approximately a second behind the three leading runners from the UK, Russia and Ukraine, each of whom had run faster than Gueï in the individual 400m event at the Championships.

With 200m remaining she still appeared out of medal contention but finished with a sprint in which she passed all the other athletes in the last 50m to win the race for France at the last stride by 0.05 seconds.

In February 2019, Gueï announced her pregnancy on her Instagram account, and gave birth to a boy on 23 April.
