The Kevin Mullen Shield is an annual subsidiary league competition organised by Louth GAA for Junior grade Gaelic football clubs in County Louth.
The competition was launched in 1978 as a junior special league, with Westerns being the inaugural winners. Local company Drogheda and Dundalk Dairies Ltd. donated a trophy to the county board for the league. In 1989 the competition gained a new sponsor in Avonmore Dairies and the Avonmore Shield was presented to that year's winners - Dowdallshill. After the 2000 death of former Seán O'Mahony's Chairman Kevin Mullen, the County Board awarded a new trophy for the league winners named in his honour.
Participating teams are split into groups, with the best performing sides qualifying for the knockout stages of the competition.
