1983–84 Ulster Cup

The 1983–84 Ulster Cup was the 36th edition of the Ulster Cup, a cup competition in Northern Irish football.

Glentoran won the tournament for the 7th time and 3rd consecutive season, defeating Coleraine 5–2 in the final.

Similar to the Gold Cup, there was a change in the format of the tournament this season due to two additional clubs competing. Section A clubs played each other twice and played three matches with Section B clubs (and vice versa for Section B clubs). Section C clubs played each other once and played four matches with Section D clubs (and vice versa for Section D clubs). The clubs that topped each section progressed to the semi-finals.
