Qualification
The top 12 teams in this event at the 2019 World Aquatics Championships qualified for the Olympics. An additional 4 teams will qualify through having the fastest times at approved qualifying events during the qualifying period (1 March 2019 to 30 May 2020).[3]
Competition format
The competition consists of two rounds: heats and a final. The relay teams with the best 8 times in the heats advance to the final. Swim-offs are used as necessary to break ties for advancement to the next round. The stroke order for medley relays is backstroke, breaststroke, butterfly, and freestyle. Mixed medleys must consist of two men and two women, but the choice of order (and therefore stroke) is left to the team.[4]
