Katinka Hosszú

Katinka Hosszú (Hungarian: [ˈkɑtiŋkɑ ˈhossuː]; born 3 May 1989) is a Hungarian former competitive swimmer specialized in individual medley events. She is a three-time Olympic champion and a nine-time long-course world champion. She is the owner of a Budapest-based swim school and swim club called Iron Swim Budapest, and a co-owner and was captain of Team Iron, founding member of the International Swimming League.

Hosszú held seven world records in the course of her career, and was the first swimmer (male or female) to hold world records in all five individual medley events at the same time. She holds two-thirds of the Hungarian national records. Hosszu was named FINA Swimmer of the Year in 2014, 2015, 2016 and 2018, and won SwimSwam's Swammy Award for Female Swimmer of the Year in 2013.

Hosszú competed at five Summer Olympics: 2004, 2008, 2012, 2016, and 2020. After a long tenure under head coach Shane Tusup, who was her husband, following their divorce Hosszú was coached by Dave Salo before moving onto Árpád Petrov. At the end of 2019 she parted ways with Petrov, and by the following year had hired József Nagy to be her coach.

She was one of the most versatile swimmers in the world, and was nicknamed the "Iron Lady", which she has since turned into a fast growing international brand. In 2014 she became the first race-prize dollar millionaire (man or woman) in swimming history.

In 2019, Forbes magazine considered her to be the most valuable Hungarian athlete, having ranked in the first position for the previous five years.
