The 2023 Ligue1 Québec season is the twelfth season of play for the Ligue1 Québec (and the first since rebranding from the Première ligue de soccer du Québec). L1Q is a division three semi-professional soccer league in the Canadian soccer league system and the highest level of soccer based in the Canadian province of Québec.
The two Coupe PLSQ finalists from the previous season (AS Blainville and Celtix du Haut-Richelieu) advanced directly to the Quarter-Final round. Two additional clubs (FC Laval and RS Beauport) were selected by a random draw to also advance directly to the Quarter-Final round.
The league will operate a reserve division. Each team, apart from the CF Montréal Academy, will operate a reserve team, playing each other once. Pierrefonds FC, who play in the women's division but not the men's, will field a team in the division as well
