The 6 Nations began in 2000, when Italy joined the 5 Nations championship. Since the 6 Nations came into existence and up to the end of the 2018 championship, Ireland has won it four times, in 2009, 2014, 2015 and 2018.

Going back to the 5 Nations and its various predecessors and including the 6 Nations, Ireland has won 14 championships, 8 of which they were joint winners.
