The squad is for Ireland's Nations League opener against Wales.
Ireland will kick-off their Nations League campaign against Wales on 6 September, and this is the squad that they'll do it with.
West Ham's Young Player of the Year Declan Rice is not in the squad, amid speculation that he may wish to represent England.

Martin O'Neill has given goalkeeper Sean McDermott, who plays for Kristiansund BK in Norway's Eliteseruen, his first senior call-up.
Other than that decision the squad is full of recognisable names.
Other notable omissions include James McCarthy who has a leg injury, Robbie Brady who has been out for almost a year, and strikers Scott Hogan and Sean Maguire.
This squad is just provisional, and an updated one will be announced on 3 September ahead of the competitive game against Wales, as well as a friendly versus Poland.
