The Ligue de Baseball Junior Élite du Québec (LBJEQ) is the top-level amateursummer baseball league in the Canadian province of Quebec. It is composed entirely of junior elite players - the best baseball players in the province under 22 years of age.
The league began as the Ligue de Baseball Royale junior, founded in 1948 by Gérard Thibault. In 1995 the league, now known as the Ligue de baseball Montréal Junior Élite merged with the eastern Quebec based Ligue Junior Majeure du Québec. Two years later the league assumed its current name.
