The 1983–84 Cypriot Cup was the 42nd edition of the Cypriot Cup. A total of 41 clubs entered the competition. It began on 13 November 1983 with the preliminary round and concluded on 9 June 1984 with the final which was held at Tsirion Stadium. APOEL won their 12th Cypriot Cup trophy after beating Pezoporikos 3–1 in the final.
In the 1983–84 Cypriot Cup, participated all the teams of the Cypriot First Division, the Cypriot Second Division and the Cypriot Third Division.
The competition consisted of six knock-out rounds. In all rounds each tie was played as a single leg and was held at the home ground of one of the two teams, according to the draw results. Each tie winner was qualifying to the next round. If a match was drawn, extra time was following. If extra time was drawn, there was a replay at the ground of the team who were away for the first game. If the rematch was also drawn, then extra time was following and if the match remained drawn after extra time the winner was decided by penalty shoot-out.
The cup winner secured a place in the 1984–85 European Cup Winners' Cup.
In the first preliminary draw, participated all the 14 teams of the Cypriot Third Division and 6 of the 14 teams of the Cypriot Second Division (last six of the league table of each group at the day of the draw).
One of the Cypriot Third Division teams was Ethnikos Defteras, a team which had been promoted from the amateur divisions. However, they were expelled from Cyprus Football Association after Cyprus' Court of Arbitration for Sport decision, after Doxa Paliometochou's objection based on a federation's regulation in which teams of villages with population under 1500 people couldn't join the federation. Ethnikos Defteras resorted to the court. Before the court's decision to be known, the draw of the preliminary round made, including Ethnikos Defteras. They were drawn against 1983–84 Cypriot Third Division team, Ethnikos Assia F.C. During the draw, Cyprus Football Association announced that if the court's decision hadn't been known in two weeks after the draw (and the other teams would have already played their qualifying matches), the opponent of Ethnikos Defteras would advance to the next round without playing any match, thing which it happened.
