The Wexford County Board of the Gaelic Athletic Association has organised it since 1903.
The all-time record-holders are Ferns St Aidan's, who have won the competition five times.
The Wexford Junior Hurling Championship dates back to 1903.
The championship features a group stage before the top-ranking teams complete a knock-out series of games.
They often do well there with the likes of Fethard St Mogues among the clubs from Wexford to win at least one Leinster Championship after winning the Wexford Junior Hurling Championship.
