The tournament was contested by England, France, Ireland, Scotland, and Wales.

The championship was won by Wales, their twentieth outright win in the competition.

Having won all four of their games, Wales also won the Grand Slam for a record eighth time - Wales had formerly shared the record of seven with England.

Victories over England, Ireland and Scotland (the Home Nations), also meant Wales won the Triple Crown for the third consecutive time, a record, given no other team had ever won the Triple Crown more than twice in a row.

It was Wales' fifteenth in total, also a record, surpassing the fourteen won by England.
