2021 national road cycling championships

The 2021 national road cycling championships were held throughout the year and were organised by the UCI member federations. They began in Qatar with the men's time trial event on 26 January.

Jerseys
The winner of each national championship wears the national jersey in all their races for the next year in the respective discipline, apart from the World Championships and the Olympics, or unless they are wearing a classification leader's jersey in a stage race. Most national champion jerseys tend to represent a country's flag or use the colours from it, like the Spanish and British jerseys, respectively. Jerseys may also feature traditional sporting colours of a country that are not derived from a national flag, such as the green and gold jerseys of Australian national champions.
