The 2018 BC Lions season was the 61st season for the team in the Canadian Football League (CFL) and their 65th overall. The Lions improved upon their 7–11 record from 2017 and clinched a playoff berth following a week 19 win over the Edmonton Eskimos. They returned to the playoffs following a one-year absence where they missed the playoffs for the first time since 1996. However, the team lost the East Semi-Final to the Hamilton Tiger-Cats by a 40-point margin, which is the largest in the Lions' playoff history.
