Jay Vine (born 16 November 1995) is an Australian professional racing cyclist who currently rides for UCI WorldTeam .
In December 2020, Vine was initially announced to be joining UCI Continental team for the 2021 season. However, as a result of winning the 2020 Zwift Academy program, he earned a professional contract with Belgian UCI ProTeam .
Vine made his Grand Tour debut in the 2021 Vuelta a España, ultimately placing 73rd. He also featured in several breakaways, the most notable of which were on stages 12 and 14. On stage 12, he was the last remaining rider of a late breakaway attempt and was caught inside the final kilometre. Two stages later, with left, Vine dropped back to his team car, and as he was collecting something, he drifted into the side of the car and crashed. He suffered moderate road rash but was able to recover and place third on the summit finish to Pico Villuercas. As a result of his performances during the Vuelta, extended his contract by two years.
On 26 February 2022, Vine won the men's race at the 2022 UCI Cycling Esports World Championships.
In August 2022, Vine rode his second Grand Tour at the Vuelta. On stage six, which finished atop the climb of Pico Jano, Vine attacked from the GC group at around from the finish. After catching and passing Mark Padun, the remaining lone breakaway rider, Vine held off the GC contenders to win the stage, taking his first win as a professional. He finished 15 and 16 seconds ahead of Remco Evenepoel and Enric Mas, respectively. Two days later, on the race's second mountaintop finish, Vine got into the break that contested the stage win. On the final climb of Collau Fancuaya, Vine dropped his breakaway companions to take his second stage win of the race, taking the lead in the mountains classification in the process. He crashed out of the race on stage 18 while wearing the polka dot jersey.
In April 2024, Vine fractured a cervical and two thoracic vertebrae in a crash during the Tour of the Basque Country. It was feared that he might never walk again, but he was back racing four months later in the 2024 Vuelta a España where he won the mountains classification for the first time. He went on to represent Australia at the 2024 UCI Road World Championships in Zurich, winning a gold medal in the mixed team relay along with fellow Canberran Michael Matthews. He was named men's athlete of the year in the 2024 Canberra Sports Awards.
On 28 August 2025, Vine won the 6th stage of the 2025 Vuelta a España, thus moving into the lead in the race's mountains classification (the polka dot jersey). He was named men's athlete of the year in the 2025 Canberra Sports Awards.
In January 2026, Vine won the General Classification of the 2026 Tour Down Under, despite a crash on the final stage following a kangaroo hopping into the peloton, in which Vine broke his wrist.
Vine and his wife Bre, fellow cyclist/full time manager support, live in Andorra. On 14 August 2024, just before his start at the 2024 Vuelta a España, they welcomed their first son.
