King was born and raised inEvansville, Indiana, the daughter of Mark and Ginny King. Mark ran track and cross-country atIndiana State University, and Ginny swam forEastern Kentucky University andIllinois State University. King's younger brother Alex is a walk-on swimmer at theUniversity of Michigan.[6] King attendedFJ Reitz High School, where the school's swim team shared Lloyd Pool with five other teams.[6] The lanes at Lloyd Pool were often overcrowded, preventing King from receiving the necessary workout she required to perform at her best competitive level, so to help compensate, King added several morning practices a week with the local masters team and joined a competitive swim team called the Newburgh Sea Creatures.[6]
To gain additional competition experience in her teenage years, King swam unattached at junior national championships, with a standout performance in the 200-yard breaststroke at the 2012 Winter Junior National Championships.[7] As a 17-year-old at the2014 Junior Pan Pacific Swimming Championships, held inHawaii, she won gold medals in the 100 meter breaststroke with a Championships record time of 1:07.98, and the 4×100 meter medley relay with a Championships record of 4:03.44, and placed fourth in the 200 meter breaststroke with a time of 2:29.83.[8]
King attendedIndiana University Bloomington, where she competed for theIndiana Hoosiers swimming and diving team.[5]
At theNCAA Women's Division I Swimming and Diving Championships during her first year, she was the NCAA Champion in the 100 yard breaststroke (56.85) and 200 yard breaststroke (2:03.59). The performance established King as one of the best short course yards breaststroke swimmers in history, setting theAmerican, NCAA, NCAA Meet, U.S. Open, Indiana school, Big Ten, and Georgia Tech Pool records in winning the NCAA titles.[5][9] That same first year she was named the Big Ten Swimmer of the Year, earned four All-America honors, First-Team All-Big Ten, and Big Ten Freshman of the Year.[5] King continued her elite success by claiming the 100 yard breaststroke and 200 yard breaststroke titles throughout her collegiate career and was only the 2nd swimmer ever to sweep the two events for all four years. As a senior, she won theHonda Sports Award as the nation's best female swimmer.[10][11]

In the100-meter breaststroke heats, King finished first with a time of 1:05.78 and qualified for the semifinals. There she again finished first with a time of 1:05.70. The next fastest swimmer wasYuliya Yefimova from Russia, the reigning world champion who had previously served a 16-month doping suspension for failing a 2013 drug test. Yefimova also failed a drug test in 2016, but with no research on how long the drug stayed in a person's system, she was not banned or given a suspension.[12] As King looked on from the ready room, where swimmers gather before they race, Yefimova won her semifinal and wagged her index finger, apparently in imitation of King's own finger wag in an earlier heat. After posting the fastest time in the 100 m breaststroke semifinals, King expressed distaste. In a post-race interview withNBC and reported on byThe New York Times, King said, "You wave your finger No. 1 and you've been caught drug cheating? I'm not a fan."[13] King went on to win the Olympic gold medal in the 100-meter breaststroke, setting an Olympic record of 1:04.93 in the process.[14]

She did not qualify for the final.[15] Charlotte Wilder ofUSA Today said King and Yefimova's rivalry "was heightened by the backstory, the international rivalry, and the high stakes of a final event. It was the Olympics at its very, very best."[16] Mike Decourcy and Tom Gatto ofSporting News noted the two swimmers "joined the list of the hottest U.S.-Soviet/Russian head-to-heads in sports history."[17] As a result of her approach to the 2016 Summer Olympics and her rivalry with Yefimova, Pat Forde ofYahoo! Sports said King developed a reputation as being "friendly but fiery, with no filter and no apologies."[6] Journalists fromThe Washington Post and theAssociated Press criticized King's treatment of Yefimova.[18][19]
At the2017 US Nationals, the qualification meet for theWorld Aquatics Championships inBudapest, King swept the breaststroke events. She won the 50-meter breaststroke with a time of 29.66, the 100-meter breaststroke with 1:04.95, and the 200-meter breaststroke with 2:21.83.
