The 2018 Alberta Senior AAA Playoffs are the province of Alberta's qualifying tournament for what would be the spot in the McKenzie Cup which would have been the final qualifier for the Pacific region spot in the 2018 Allan Cup. However, due to no teams being registered at the Senior AAA level for the 2017-18 season in British Columbia it will be the final qualifier for the Allan Cup.
The former Chinook Hockey League (now Allan Cup Hockey West as of the 2017-18 season) league playoffs have recently served as the province's Senior AAA playoffs as all of the registered teams at the Senior AAA level in the province also have made up the whole membership of the league. But for the 2016-17 season the Rosetown Red Wings who are based out of Rosetown, Saskatchewan joined the league. They opted out of the league playoffs for the 2016-17 season to compete for the Western region Allan Cup berth against the Manitoba champion in the 2017 Rathgaber Cup. However, as they are already qualified for the 2018 Allan Cup as the host team they are participating in the league playoffs which will be a single elimination tournament held over one weekend at one site and the other four members of the league will hold a provincial playoff seperate of the league playoffs. There will be two rounds of best-of-seven series with the tournament winner advancing the the Allan Cup
- Lacombe Generals defeated Fort Saskatchewan Chiefs 4 games to none
- Stony Plain Eagles defeated Innisfail Eagles 4 games to 1
