Linfield will take on SSE Airtricity Premier Division champions Dundalk in the first ever Unite the Union Champions Cup next month.
The two sides will meet over two legs - the first on Friday, November 8 at Windsor Park and the return leg at Dundalk's Oriel Park on Monday, November 11.
Both clubs will each receive €25,000 for competing in the game, with the winners pocketing an additional €25,000 in sponsorship money from trade union Unite.
Another €25,000 will be awarded to both teams, which will be earmarked for community-based projects in the Belfast area.
It is the first time teams from the north and south will compete against each other in a competitive cross-border competition since the Setanta Sports Cup ended in 2014.
"This is a hugely exciting tournament and one that will bring benefits to clubs and the wider football family in Northern Ireland," said Irish FA chief executive Patrick Nelson at the tournament's launch.
"I am looking forward to the games in November and to seeing this tournament become a regular fixture on the football calendar - north and south."
Linfield 's home game against Dungannon Swifts, which was set for Saturday, November 9, has been postponed as a result of these fixtures.
