England has won the most Six Nations Championships.
England has won the championship outright or shared the title more times than any other nation in the competition’s history. Its record includes the earlier Home Nations and Five Nations eras, which are treated as part of the championship lineage.
The modern Six Nations began in 2000, when Italy joined England, France, Ireland, Scotland and Wales. England’s strongest modern periods include its Grand Slam in 2003 and a run of four titles from 2020 through 2023, including the 2020 championship.
Records can differ if a source counts only outright titles or excludes shared championships. The standard historical championship table counts both outright and shared wins, and it includes the Home Nations and Five Nations predecessors.
