The MacNaughton Cup is a trophy awarded annually to the regular season conference champion of the Central Collegiate Hockey Association (CCHA).

The trophy is named after James MacNaughton of Calumet, Michigan, who was a supporter of amateur ice hockey.

[1] In 1913, MacNaughton purchased a cup trophy for US$2,000[2] and donated it to the President of the American Hockey Association, which was to be awarded to the league's champion at the end of the season.

In 1951, the MacNaughton family arranged to have the Cup awarded to the newly founded Midwest Collegiate Hockey League (MCHL), a precursor to the WCHA.

Michigan Tech left the WCHA to join the Central Collegiate Hockey Association (CCHA) for the 1981–82 season.
