Briana Williams

At the 2019 CARIFTA Games Williams again tripled in the 100 m, 200 m, and 4 × 100 m relay to win three gold medals in the under-20 category, and was the first Jamaican to earn the games' Austin Sealy award two years in a row since Usain Bolt in 2004.

Williams ran 10.94 s in the 100 m final at the Jamaican Championships on 21 June 2019, which would have set the world youth (under-18) best time and improved her Jamaican junior record. However, she tested positive for the banned diuretic hydrochlorothiazide during the competition. She was ruled to be not at fault and received no period of ineligibility to compete, but her results from the Jamaican Championships were nullified.

Her 11.02 s personal best from earlier that June, set at the Great Southwest Classic in Albuquerque, New Mexico, remains the Jamaican junior record. Her 11.10 s personal best before that, set at the JAC Open in Jacksonville, Florida a week earlier, was also the Jamaican junior record at the date of setting. Her personal best before that, 11.13 s set in March 2018, is the world age-15 record.

Briana Nichole Williams (born 21 March 2002) is an American-born Jamaican female sprinter who is the world age-15 record holder, and the Jamaican junior (under-20) record holder in both the women's 100 metres and 200 metres. She earned gold medals in the 100 metres, the 200 metres, and the 4 × 100 metres relay at the 2018 CARIFTA Games in the under-17 category, setting championship records in the 100 metres and 4 × 100 metres relay, earning her the games' Austin Sealy award. Later that year she became the youngest girl ever to win both the 100 metres and the 200 metres at the 2018 IAAF World U20 Championships in Tampere. For her athletics achievements in 2018 she was nominated for the IAAF Female Rising Star and the Laureus Breakthrough of the Year awards.
