League1 Alberta (L1AB) is a semi-professional men's and women's soccer league in Alberta, Canada. The league is sanctioned by the Canadian Soccer Association and the Alberta Soccer Association as a third division pro–am league in the Canadian soccer league system.
In the Canadian soccer league system, the men's division is behind the Canadian Premier League (CPL). It is part of League1 Canada, the national third tier with regional division, with L1AB equivalent to Ligue1 Québec (L1Q), League1 Ontario (L1O), and League1 British Columbia (L1BC). The men's league champion qualifies for the Canadian Championship, the domestic cup championship, while the women's league champion qualifies for the League1 Canada Women's Inter-Provincial Championship.
