They'll head to Marbella for a training camp.
The FAI has confirmed three friendly matches for the Republic of Ireland Under-21s in Spain this summer.
Jim Crawford's side will take on Switzerland on May 30th.
They will then face Australia’s Olympic team on June 2nd before taking on Denmark on June 5th.
The camp takes place in Marbella.
Manager Jim Crawford said: “We were determined to get a number of games in the June international window for the players to have the best possible preparation for our qualifiers.
“It is excellent news that this has been confirmed, all three teams present exciting and challenging opposition to our team and myself and the staff can’t wait to get back with the players to test ourselves against this standard of opposition.”
Crawford has spoken previously about the importance of having a run of games in the summer international window to build squad cohesion.
He added: “I saw how the Toulon Tournament in 2019 gave a lot of the players involved in the Under-21s a platform for their club form and the confidence to go play at this level.
“Having these games in Marbella gives us an opportunity to give a talented group match minutes and a chance to come together over 10 days, work hard, work on our style of play and get ready for September.”
All games will be behind closed doors with no admittance from the public.
