Ireland won the 2024 Six Nations Championship in rugby union.
Ireland secured the title by finishing first in the championship table after the five-round tournament. The 2024 competition was played by England, France, Ireland, Italy, Scotland, and Wales from February to March.
Ireland opened the tournament with a 38–17 victory over France in Marseille and followed it with wins over Italy and Wales. Its title was confirmed before the final round, although England defeated Ireland at Twickenham in the last matchday.
Ireland’s 2024 championship was its second successive Six Nations title. It did not complete a Grand Slam because England’s victory ended Ireland’s perfect record, so the championship and the Grand Slam are not interchangeable terms.
