The Dublin and Belfast Inter-city Cup was a soccer competition that ran for eight seasons in Ireland between and including 1941/42-1948/49. Each season's competition consisted of six teams from each of the two jurisdictions on the island of Ireland, the Irish Football Association and the Football Association of Ireland. Played in knock out format, the matches were played on a two leg basis. Dalymount Park, Dublin was used as the home venue by all the League of Ireland clubs. For the second round of the competition, the six first round winners were joined by the two best losers. It was an extremely popular competition, adding variety to the restricted war-time football diet and generated much needed and significant revenues to the competing clubs.
