Jessica Esther Fox OAM (born 11 June 1994) is a French-born Australian Olympic and world champion slalom canoeist.

Her ten gold medals in individual events make her the most successful paddler, male or female, in World Championship history.

[7] Fox was born in Marseille, France, and when she was four years old, she moved to the suburb of Penrith, in Sydney, with her family.

[18][19] Fox races in K1, C1 and Kayak Cross events and is coached by her mother, Myriam.

[23] At the 2010 Summer Youth Olympics in Singapore, she won the gold in the girls' K1 slalom event.

She won her first World Cup by taking out the C1 event at the third round in La Seu d'Urgell.

[10] At the 2011 World Championships in Bratislava, Slovakia, she finished 19th, which gave Australia an automatic spot in the event at the 2012 Summer Olympics.

[10] She won silver medals at Australian Open and the Oceania Championships in the women's K1 event in 2011.

[10] In 2012, Fox was selected to represent Australia for the first time at the Olympics in the women's K-1 event, where she won the silver medal at the age of 18.

[18] Her result has been described as competitive revenge against the 44-year-old Czech paddler Štěpánka Hilgertová, who had beaten Fox's mother Myriam to the K-1 gold medal sixteen years earlier in the 1996 Summer Olympics.

[25] At the 2020 Tokyo Olympics, held in 2021 due to the COVID-19 pandemic, Fox finished third to win the bronze medal in the Women's K-1.

[29] Fox was also the fastest qualifier for the final of the inaugural Women's Canoe Slalom C-1 event at the Olympics, where she went on to win her first Olympic gold medal, beating silver medalist Mallory Franklin of Great Britain by more than three seconds with a penalty-free run.

[30] At the 2021 World Championships in Bratislava, Fox did not progress to the final of either the K1 or C1 for the first time in her entire career, after incurring 50-second penalties in the semi-finals of both.

[31] Fox was selected as the opening ceremony flag bearer to represent Australia at the 2024 Summer Olympics in Paris, France.

Fox was the 2010 Penrith Press Junior Sports Star of the year and NewsLocal Medal winner.

In August 2024, Fox filled in for Alex Cullen on the Nine Network's Today as a sport presenter.
