The Six Nations Championship is an annual international men's rugby union competition between the teams of England, France, Ireland, Italy, Scotland and Wales. It is also the oldest sports tournament ever between Home Nations. The championship holders are Ireland, who won the 2024 tournament.

Rugby union football, commonly known simply as rugby union or more often just rugby, is a close-contact team sport that originated at Rugby School in England in the first half of the 19th century. Rugby is simply based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends.
