He'll leave his role from European Affairs to take over from Simon Coveney.
Peter Burke has been appointed the Minister for Enterprise.
The Longford Westmeath TD leaves his role in European Affairs to replace Simon Coveney, who announced he would be standing down earlier this month.
He will be replaced as a Junior Minister in the European Affairs brief by Jennifer Carroll-MacNeil.
Elsewhere in Simon Harris' new Cabinet, Patrick O'Donovan will step into the Taoiseach's former role as Higher Education Minister, while Helen McEntee, Heather Humphreys and Pascal Donoghue will remain in their current roles.
Hildergard Naughton will remain as the Chief Whip, but with a new brief on special needs.
TD’s will shortly vote in the Dail chamber on the new Government Ministers, before the new appointees head to Aras an Uachtarain, where they will receive their seals of office from the President.
