The Junior International Quadrangular Tournament (most recently known as the Umbro Trophy for sponsorship reasons) was a football tournament held on an irregular basis between junior representative teams from Northern Ireland, the Republic of Ireland and Scotland and the Isle of Man national team.

Scotland are the tournament's most successful side having won six of the twelve editions.

[2][3] Each tournament is rotated around the competing teams who take it in turn to act as hosts.

Initially the competition was held on a knock-out basis with two semi-finals followed by a third-place play-off and final.

Since 2001 it has been held on a round-robin league basis, with each team facing each other once and three points being awarded for a win and one for a draw.
