The 2019 IAAF World Athletics Championships was the seventeenth edition of the biennial, global athletics competition organised by the International Association of Athletics Federations (IAAF), since renamed World Athletics. It was held between 27 September and 6 October 2019 in Doha, Qatar, at the renovated multi-purpose Khalifa International Stadium, but reduced to 21,000 available seats. 1,772 athletes from 206 teams competed in 49 athletics events over the ten-day competition, comprising 24 events each for men and women, plus a mixed relay. There were 43 track and field events, 4 racewalking events, and 2 marathon road running events. The racewalking and marathon events were held in Doha Corniche.

The next event was to have been held in 2021, but the 2021 Summer Olympics rescheduling as a byproduct of the COVID-19 pandemic forced World Athletics to change the date a year on 30 March 2020.
