Christian Coleman (born March 6, 1996) is an American professional track and field sprinter who competes in the 100 metres and 200 metres. He is the current world champion in the 100 meters. He was a double medallist at the World Championships in Athletics in 2017, winning silver medals in both the 100 m and 4 × 100-meter relay. He holds personal records of 9.76 seconds for the 100 m and 19.85 for the 200 m, and is also the world indoor record holder for the 60 metres with 6.34 seconds. He was IAAF Diamond League champion in 2018 and the world number one ranked runner in the 100 m for the 2017 and 2018 seasons.
Coleman represented the United States in the relay at the 2016 Summer Olympics, competing in the heats only. He was the gold medallist in the 60 m at the 2018 IAAF World Indoor Championships and is a two-time American national champion, having won the 60 m in 2018 and 100 m in 2019. Coleman competed collegiately for the Tennessee Volunteers and won five NCAA titles indoors and out, including American collegiate record performances in both the 100 m and 60 m.
On June 17, 2020, it was announced that Coleman was provisionally suspended from competition due to a missed drug test dating back to December 9, 2019. On October 27, it was announced that Coleman had been banned until May 13, 2022, missing the 2020 Summer Olympics. He later appealed the decision to the Court of Arbitration for Sports that reduced his suspension to a year, citing that Coleman never tested positive for PEDs, but he would still miss the 2020 Summer Olympics.
