Northern Ireland will appear in their first major tournament since the 1986 World Cup in Mexico. It will also be their first ever European Championships.
The nation qualified for the Euros by coming top of Group F, beating the likes of Romania, Hungary and Greece.
Northern Ireland manager Michael O’Neill has selected his 23 man squad to face Ukraine, Poland and world champions Germany.
His squad includes 11 players from the Football League.
Oliver Norwood from Reading, Corry Evans of Blackburn Rovers, Stuart Dallas at Leeds United, Jamie Ward of Nottingham Forest and Shane Ferguson from Millwall are the Football League’s representatives in midfield.
Conor Washington of Queens Park Rangers, and Will Grigg from Wigan Athletic are both in the squad as attackers, and are expecting to represent the Football League from the start for their country.
O’Neill’s men take on Poland in their first match on June 12, before facing Ukraine on June 17. Their final group match is against World Champions Germany on June 21.
