The broadcaster says the new Irish Government and Brexit have spurred the move
British broadcaster Sky News is opening a bureau in Dublin.
It says this is to "strengthen its presence" in Ireland.
Darren McCaffrey will become Dublin correspondent and be permanently based in the capital.
There will also be a dedicated crew to cover Irish news stories, Sky says.
Originally from Fermanagh, McCaffrey is currently UK political correspondent with the broadcaster.
He has covered politics for the past seven years, including a stint in Brussels post the Brexit result.
In a statement, Sky says: "As a newly appointed Irish Government settles in Leinster House and Brexit negotiations begin in full force, Darren will examine Ireland’s place within the EU and its future trade negotiations with the UK.
"Sky News' long-standing Ireland correspondent, David Blevins will work alongside Darren by continuing to cover news across the country."
John Ryley, head of news at Sky, said: "With a post Brexit world upon us there has never been a better time to expand our presence in Ireland.
"Darren is a great talent and he will work alongside David Blevins to ensure we have comprehensive coverage across the entire country, bringing the latest news and analysis to our viewers both north and south, in the UK and around the world."
On his new role, McCaffrey added: "Brexit is not just an issue for Britain but presents threats and opportunities here in Ireland too.
"It will be a fascinating time to return home to cover decisions to be made in Dublin, decisions which will shape these two islands and indeed Europe for years to come."
McCaffrey will start in Dublin in September.
Sky has previously had a full staff based in the capital, during the inception of Sky News Ireland.
The regional version of Sky News broadcast from its studios in Dublin from 2004 to 2006.
