Cian Uijtdebroeks (born 28 February 2003) is a Belgian road cyclist, who currently rides for UCI WorldTeam Visma–Lease a Bike. Uijtdebroeks is considered to be a very promising talent, and has been compared to Remco Evenepoel. He made his professional debut in 2022 and won the Tour de l'Avenir. He made headlines at the 2023 Vuelta a Espana where he finished eighth overall in his grand tour debut. In December 2023 he signed for Team Jumbo Visma for a four year deal until 2027, but his current team, Bora–Hansgrohe, would dispute this, saying that he was contracted through 2024 with the team. Eventually, the parties reached an agreement for Cian to ride with Team Visma-Lease a Bike in 2024.
