Ireland national under-20 rugby union team

The Ireland national under-20 rugby team was formed in 2006, having previously been known as the under-21 team.

History
Ireland have won the Grand Slam four times and the Six Nations Championship five times: 2007, 2010, 2019, 2022 and 2023. In the pandemic-truncated competition in 2020, Ireland won the Triple Crown. At the time the competition was halted, Ireland were undefeated and led the table. However, this was not considered a championship nor a grand slam. Ireland won two consecutive Grand Slams in the 2022 and 2023 Six Nations championships, but were denied a third consecutive Grand Slam and championship title following a draw away to England. Despite Ireland and England having both recorded four wins and a draw, England were crowned champions as they had earned one more try bonus point than Ireland.

Current squad
Head coach Willie Faloon named his 30–man squad for the 2024 U20 Rugby Championship on 14 June.
