1997–98 Irish League Cup

The 1997–98 Irish League Cup (known as the Wilkinson Sword League Cup for sponsorship reasons) was the 12th edition of the Irish League Cup, Northern Ireland's secondary football knock-out cup competition. It concluded on 9 September 1997 with the final.

Crusaders were the defending champions after their first League Cup win last season; a 1–0 victory over Glentoran in the previous final. This season they went out in the quarter-finals to eventual winners Linfield, who lifted their fourth League Cup with a 1–0 victory over arch-rivals Glentoran in the final, condemning the Glens to their second successive League Cup final defeat.

This was the last competition to feature clubs from the Irish League B Division. From the following season onwards, the competition would only be open to senior clubs in the top two divisions.
