At the 2019 World Aquatics Championships held in Gwangju, South Korea, he first won a gold as part of the team in Men's 4 × 100 m freestyle relay.[24] He then won gold in the 50m butterfly, an event he failed to win in 2017. He is the first American man to win that event, and he set a new national and championship record time of 22.35 second for the event.[25] This is followed by a national record and the third fastest time in history (46.96) in the 100m freestyle.[26]He did so in a textile suit, which is substantially less buoyant than the full body suit used to set the record.

In the 100m butterfly event, Dressel broke Michael Phelps' ten-year-old record by 0.32 second in the semi-final, setting a new world-record time of 49.50 seconds.[27] He won gold in the final the following day. That same day within two hours, Dressel won two further golds – in the 50m freestyle in a Championships record time, and as part of the team in the mixed 4x100-meter freestyle relay, which was won in a world-record time of 3 minutes, 19.40 seconds.[28] This is a repeat of his achievement in Hungary in 2017, and it is also the first time anyone has won three gold medals in a single day at the Championships twice.[29]

In the final day of the Championships, Dressel helped United States win a silver in the men's 4 × 100 metre medley relay.[30] The medal is the eighth that Dressel won at the Championships, and the most anyone has won at a single Championships.[31] He was named FINA male swimmer of the meet, which he also won in 2017.[32]

In 2019 he was a member of the inaugural International Swimming League representing the Cali Condors, who finished third place in the final match in Las Vegas, Nevada in December. Dressel won the MVP in all 3 matches he participated in as well as winning the skins race each time. Dressel swam the 50 Freestyle in Las Vegas and beat Florent Manaudou's world record by going a 20.24. He also won the 100 Freestyle, 100 Butterfly, and 50 Butterfly.[33][34][35]

Continuing to represent the Cali Condors, Dressel broke four world records in the 100-meter butterfly (at 47.78 seconds) and the 50-meter freestyle world record, which he already held (to 20.16 seconds). He is the first man to swim the 100-meter butterfly in less than 48 seconds.[36] He also broke his own 100 IM record twice, dropping it to 49.88 the first time, and 49.28 the second time.[37] These two record breaks occurred one weekend after he was the first swimmer to ever do the 100-meter individual medley in under 50 seconds.[38]

In August 2020, SPIRE Institute and Academy signed Dressel to become one of their swimming ambassadors.[39] As an ambassador he will lead and instruct select classes.[40]
