2022–23 Northern Ireland Football League Cup

The 2022–23 Northern Ireland Football League Cup (known as the BetMcLean Cup for sponsorship purposes) was the 36th edition of Northern Ireland's football knockout cup competition for national league clubs, and the eighth edition of the competition as the Northern Ireland Football League Cup. The competition was contested by the 36 member clubs of the Northern Ireland Football League, commencing on 6 August 2022 with the preliminary round and concluding with the final on 12 March 2023. The competition was sponsored by McLean Bookmakers, the title sponsors of the cup since the 2017–18 season.

Cliftonville were the defending champions, following a 4–3 win over Coleraine after extra time in the 2022 final to win the cup for the sixth time overall. However, this season they were eliminated by the same opponents in the semi-finals. Linfield were the eventual winners, after they defeated Coleraine 2–0 in the final to win the competition for a record-extending 11th time overall, their first win since the 2019 final. Coleraine finished as runners-up for the second consecutive season after their seventh defeat in a League Cup final overall. This set a new record in the competition for the most defeats in a final.
