The 2015 BC Lions season was the 58th season for the team in the Canadian Football League and their 62nd overall. The Lions qualified for the playoffs for the 19th straight year, but lost the West Semi-Final game to the Calgary Stampeders. This was the team's first and only season under new head coach, Jeff Tedford, former head coach at California, and the 13th under general manager Wally Buono.
