Mirna Jukić (born 9 April 1986) is a retired Austrian swimmer of Croatian origin who won a bronze medal in both short course and long course at the world championships in swimming. She is trained by her father Željko Jukić, a former basketball player. She has had numerous European and World championship successes.
Jukić was born in Novi Sad (Serbia, then SFR Yugoslavia) and grew up in Vukovar, Croatia. In November 1991, the family moved to Zagreb, and her father started training her at Mladost in 1996. Her brother, Dinko Jukić, with whom she was trained early on, also became an international-level swimmer. In the autumn of 1999, the family moved to Vienna, Austria, and the same year Mirna became an Austrian citizen. Her brother became an Austrian citizen in 2000, while the parents remained Croatian citizens.
For the 2004 and 2008 Olympics, Jukić trained at The Race Club, a swimming club founded by Olympic swimmers Gary Hall, Jr. and his father, Gary Hall, Sr. The Race Club, originally known as "The World Team," was designed to serve as a training group for elite swimmers across the world in preparation for the 2000 Sydney Olympic Games. To be able to train with the Race Club, one must either have been ranked in the top 20 in the world the past 3 calendar years or top 3 in their nation in the past year. The Race Club included such well known swimmers as Roland Mark Schoeman, Mark Foster, Ryk Neethling, Ricardo Busquets and Therese Alshammar.
