1927–28 Boston Bruins season

The 1927–28 Boston Bruins season was the team's fourth in the NHL. The Bruins finished first in the American Division, marking its first division title in franchise history and its second playoff appearance. The team lost in the playoffs to the eventual Stanley Cup champion New York Rangers.

For the second straight season, Harry Oliver led the Bruins in scoring, and although the team's attack was relatively anemic – the Bruins finished with 77 goals, leading only the last-place teams in both divisions, the Chicago Black Hawks and the New York Americans – they cut down sharply in goals allowed, leading the division behind Hal Winkler's goaltending. Eddie Shore was the team's great star, finishing just one point behind Oliver in scoring and leading the league in penalty minutes by a wide margin.

Winkler in his own turn had fifteen shutouts, tied with Alex Connell for the league lead and a new NHL record; Winkler's mark remains the Bruins' single-season record for shutouts, eighty years later. Although veteran Sprague Cleghorn was fading and missed a quarter of the season with injuries, Shore and defense partner Lionel Hitchman were ironmen, playing most of each game.

Prominent newcomers included Dutch Gainor and Dit Clapper, both of whose rights were purchased from the minor leagues, and who would make a significant impact with the Bruins down the years.

With Boston's first place finish, the Bruins became the first team to win the Prince of Wales Trophy, awarded for the first time in this season.
