Manager Giovanni Trapattoni confirmed his side on Monday afternoon.
McClean's recent performances for club side Sunderland have earned him his spot, despite the 23-year-old having previously only been capped once at senior level as a substitute.
Fellow Derryman Darron Gibson also features in the Republic side.
Wigan's James McCarthy has withdrawn after his father was diagnosed with cancer.
"I have discussed this with the manager - he was very understanding and I thank him sincerely for that," McCarthy said, in a statement issued by the FAI.
"I take this opportunity to re-affirm my complete commitment to playing for the Republic of Ireland. It is a huge honour and source of great pride for me and my family.
"Despite not being present, I would like to wish the manager and my team-mates every success at the tournament and hope that Irish fans can understand the reason for my decision at this difficult time."
