Justin Alexander Gatlin (born February 10, 1982) is a retired American sprinter who competed in the 60 meters, 100 meters, and 200 meters. He is the 2004 Olympic Champion in the 100 meters, the 2005 and 2017 World Champion in the 100 meters, the 2005 World Champion in the 200 meters, and the 2019 World Champion in the 4 × 100 meters relay. In addition, Gatlin is the 2003 and 2012 World Indoor Champion in the 60 meters. He is a 5-time Olympic medalist and a 12-time World Championship medalist. At the World Athletics Relays, Gatlin won two gold medals in the 4 × 100 meters relay in 2015 and 2017. Gatlin is also a record 3-time Diamond League Champion in the 100 meters. He won the Diamond League trophy in 2013, 2014 and 2015.

Justin Gatlin's personal best of 9.74 seconds ranks fifth on the all-time list of male 100-meter athletes. He is a two-time 100 meters World Champion (2005 & 2017) and a two-time 60 metres World Indoor Champion (2003 & 2012). Gatlin won both the 100 meters and 200 meters at the 2005 World Championships. He is also a World Champion in the 4 × 100 meters relay, which the United States of America team won at the 2019 World Championships.

In 2001, he incurred a two-year ban from athletics for testing positive for amphetamines, later reduced to one year because of an appeal. In 2006, he incurred a further four-year ban for testing positive for testosterone, with this sanction erasing his then-world-record time of 9.77 seconds in the 100 meters.

Gatlin returned to competition in August 2010. In June 2012 at the US Olympic trials, Gatlin ran a time of 9.80 seconds for 100 metres. In May 2015 at the IAAF Doha Diamond League Gatlin broke this personal record for 100 metres by running 9.74 seconds, which remains Gatlin's personal best over the distance.
