2019 in 100 metres

The 2019 World Para Athletics Championships featured 100 m finals in 17 men's and 15 women's categories.

[4][5] Both World Championships winning times were the fastest recorded in the men's and women's divisions that year.

[8][9] In the under-20 age category, Lalu Muhammad Zohri was the fastest man that year with 10.03 (a senior Indonesian record) and Sha'Carri Richardson of the United States was the fastest under-20 woman with 10.75 (a world under-20 record and third in the senior rankings).

[10][11][12][13] In the under-18 category, Jamaicans Briana Williams (11.02) and Conroy Jones (10.32) were the fastest that year.

[14][15] Coleman's world title generated some controversy as he had successfully appealed a doping ban by the United States Anti-Doping Agency that season due to his missing three tests within a twelve-month period.
