Grand Slam (rugby union)

In rugby union, a Grand Slam occurs when one team in the Six Nations Championship beats all the others during one year's competition. This has been achieved 42 times in total, for the first time by Wales in 1908, and most recently by the Irish team in 2023. The team with the most Grand Slams is England with 13. It can also apply to the U20 and Women's Six Nations Championships.
