The Blaxnit Cup, is a defunct club football competition which featured teams from both football associations on the island of Ireland, in a similar format to the current Setanta Cup. It was inaugurated in 1967 as a cross-border competition between clubs from the League of Ireland from the Republic of Ireland and the Irish League from Northern Ireland and ran until 1974. The competition was sponsored by Blaxnit, a sock and hosiery manufacturer based in Newtownards.
The competition featured four teams from each league. The Blaxnit Cup was the third cross-border competition. Previous competitions included the Dublin and Belfast Intercity Cup 1941/42-1948/49 and the North-South Cup 1961/62-1962/63.
The tournament suffered from lack of interest and security concerns.
Finals played over two legs except 1973-74, aggregate score given.
