Interim Head Coach Eileen Gleeson, who takes the role after Vera Pauw's controversial exit, has selected her 25-player Ireland WNT squad for the opening games of the inaugural UEFA Nations League.
New Northern Ireland manager Tanya Oxtoby has also named a 23-strong squad.
Ireland will host Northern Ireland on Saturday, September 23 in Aviva Stadium to kick off their Group B1 opener in League B – which has already sold over 30,000 tickets.
Directly after that first game the Ireland squad will travel to Budapest to take on Hungary on Tuesday, September 26 in the Hidegkuti Nándor Stadium.
There are recalls to the squad for defenders Savannah McCarthy, Hayley Nolan and Éabha O’Mahony, midfielder Tyler Toland and forwards Saoirse Noonan and Emily Whelan.
Injuries rule out Niamh Fahey, Megan Campbell, Aoife Mannion, Jessie Stapleton, Claire Walsh, Tara O’Hanlon, Roma McLaughlin, Jess Ziu, Sinead Farrelly and Leanne Kiernan.
Both Áine O'Gorman and Harriet Scott have retired from international football and will be honoured ahead of the Northern Ireland game.
The squad links up on Monday, September 18 to begin preparations for the new campaign with training taking place at the FAI National Training Centre.
Meanwhile there are only three changes from the Northern Ireland squad that played in July's friendlies with Scotland and Ireland: Laura Rafferty and Ellie Mason have been called up as Kirsty McGuinness returns from injury, while Kelsie Burrows, Fi Morgan, and Danielle Maxwell are absent.
