The 1916–1917Montreal Canadiens season was the team's eighth season and eighth and last season of the National Hockey Association (NHA). The Canadiens entered the season as league and Stanley Cup champions. The Canadiens qualified for the playoffs by winning the first half of the season. The Canadiens then won the league playoff, but lost in the Stanley Cup final series to Seattle.
Harold McNamara, who had played for Cobalt in the Canadiens' first game in 1910, joined the Canadiens for this season. He would be released after the first two games and he would retire afterwards.
The games of the Cup finals were played at the Seattle Ice Arena. Games 1 and 3 were played under PCHA rules; Games 2 and 4 were played under NHA rules. In game one, Didier Pitre scored 4 goals as he led the Canadiens to an 8–4 victory. But the Mets won the next three contests to clinch the Cup, allowing only one goal in each game.
