1997–98 Irish League Cup

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.

[1][2] 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.

1 Larne were disqualified for fielding an ineligible player.
