Liechtenstein received a universality invitation from FINA to send two swimmers (one male and one female) to the Olympics. Christoph Meier made his Olympic debut by competing in the men's 400 m individual medley event while Julia Hassler made her second appearance, with the first being in London 2012. At the 2012 Summer Olympics, she was one of three athletes to compete for Liechtenstein. She swam the 400 and 800 freestyles, finishing twenty-seventh in the 400 and 17th in the 800. Meier finished eighth in his heat and twenty-second overall with a time of 4:19.19 seconds, which set a national record but did not qualify him for the finals. Hassler started in the second lane. She came second in her heat and twenty-first overall with a time of 8:38.19 seconds. Hassler was eight seconds off the slowest qualifying time of 8:25.55 seconds by Mireia Belmonte of Spain.
