Tao Geoghegan Hart ( TAY-oh GAY-gən HART; born 30 March 1995) is a British cyclist who currently rides for UCI WorldTeam Lidl–Trek. He rode for Team Sky as a stagiaire in late 2015, and joined the team permanently for the 2017 season.

He was the winner of the 2020 Giro d'Italia, taking the jersey following the final day time-trial and becoming the first winner in the history of the Giro never to wear the maglia rosa until he had won it outright. As such, he was the fifth and most recent British rider to win a grand tour (after Bradley Wiggins, Chris Froome, Geraint Thomas and Simon Yates), the second Briton to win the Giro (after Froome in 2018) and the youngest British rider to win a grand tour.
