Northern Ireland will face 2022 World Cup hosts Qatar in Crewe on May 31.
The fixture will take place at Gresty Road with a 5pm kick-off.
The sides have never faced each other before, but with Qatar basing themselves at St George's Park for a training camp and the Northern Irish FA keen to line up opponents before their Euro 2016 qualifier against Romania on June 13 the parties agreed on the date.
Northern Ireland are also hoping to set up a friendly meeting with Wales as they attempt to hone their squad in the British off-season.
Manager Michael O'Neill said: "This match will help us retain our focus as a squad into June as we prepare for the crucial Euro match against Romania."
