1999–2000 Irish League Cup

Linfield were the defending champions after their fifth League Cup win last season; a 2–1 victory over Glentoran in the previous final.

This season they won a record third successive League Cup with a 4–0 victory over Coleraine in the final to lift the cup for the sixth time overall.

The 4–0 scoreline remains the joint largest margin of victory in a League Cup final to date, with the record being equalled in 2013.

[1][2] Linfield's record of winning three consecutive League Cups was equalled by Cliftonville's three consecutive wins in 2012–13, 2013–14 and 2014–15.

It was then broken when Cliftonville added a fourth consecutive win in 2015–16.
