The 2019 UCI Road World Championships was the 92nd edition of the UCI Road World Championships, the annual world championships for road bicycle racing. It took place between 22 and 29 September 2019 in the historic county of Yorkshire, United Kingdom, the fourth to be held in the United Kingdom. The championships are traditionally hosted by a single town or city but, while each event in 2019 finished in the North Yorkshire town of Harrogate, the whole historic county of Yorkshire was the official host. Heavy rainfall caused some of the events to be re-routed and delayed.

The UCI Road World Championships are the annual world championships for bicycle road racing organized by the Union Cycliste Internationale (UCI). The UCI Road World Championships consist of events for road race and individual time trial, and as of 2019, a mixed team relay.
