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.

It was first held in 2001 as an unofficial tournament, and has been organised by Ulster GAA since 2004.

The winners go on to represent Ulster in the All-Ireland Junior Club Football Championship.

Rock St Patrick's are the most successful club, having won the competition three times.
