Gaudreau set a career high in points scored during the 2017–18 season, leading the Flames and finishing top-20 in the NHL with 84; his 60 assists finished within the top-10 for the category. He was named an NHL All-Star for the fourth consecutive year, but would not participate in the playoffs as the Flames came up short of a late-season push for the last wild card spot in the Western Conference.
