The J. Pius Callaghan Cup[1] is a trophy that was formerly given to the ice hockey Junior A Champion of Atlantic Canada from 1981 until 1991.
[2] From 1991 until 2006, the trophy was awarded to the playoff champion of the Maritime Junior A Hockey League.
Eventually, as Maritime hockey became less prominent, the Dudley Hewitt Cup went to the Central Champion only.
The Canadian Amateur Hockey Association gave the MJAHL custody over the Callaghan Cup as its playoff championship.
In 2006, the Maritime Junior A Hockey League retired the trophy and replaced it with the Kent Cup.
