The Ulster Junior Club Football Championship is an annual Gaelic football competition organised by Ulster Gaelic Athletic Association (GAA). It is played between the Junior championship winners from each of the nine counties of Ulster. The competition has a straight knock-out format. It was first held in 2001 as an unofficial tournament, and has been organised by Ulster GAA since 2004. The winners are awarded the Paul Kerr Cup. The winners go on to represent Ulster in the All-Ireland Junior Club Football Championship.
Monaghan clubs have won the competition eight times, more than any other county. Rock St Patrick's are the most successful club, having won the competition three times. The current champions are Arva from Cavan.
