Courtney Frerichs (born January 18, 1993) is an American middle-distance runner from Nixa, Missouri, who specializes in steeplechase. Frerichs placed second in steeplechase behind Emma Coburn and ahead of Colleen Quigley at the 2016 US Olympic Trials to qualify to represent the United States at the 2016 Summer Olympics. She won the silver medal at the 2017 World Championships, becoming the seventh fastest woman in the history of the event (displaced to #8 two weeks later). Emma Coburn won the gold medal at the same event, thus making Coburn and Frerichs the first female Americans to win the gold and silver medal in any individual World Championships or Olympics race longer than 400 meters since the 1912 Stockholm Games.
On July 20, 2018, at the Herculis meet in Monaco, she finished in second place behind Beatrice Chepkoech's world record 8:44.32. Frerichs' time of 9:00.85 jumped her ahead of Coburn for the American and North American (NACAC) records in the steeplechase and the #6 mark all time.
