The 1929–30 Harvard Crimson men's ice hockey season was the 32nd season of play for the program. Season Prior to the season, in order to settle the confusion caused by using professional referees in amateur games, a meeting was held at the Harvard Club so that colleges could agree on a uniform code of rules to be observed by all. The meeting specifically did not address the new offside rule that the NHL was implementing, though that probably was for the best as the NHL would have to alter its rule during the 1929–30 season to counteract the ballooning goal totals. In addition, Harvard began recording assists as an official statistic for this season. For the first time in 6 years Harvard did not open its season against MIT, instead they returned to their former home to play Boston University. Despite the change in opponent, Harvard still won its inaugural game though both teams weren't particularly sharp in the contest. In their annual contests against Canadian colleges, Harvard fell to Toronto twice but then rebounded after shuffling their lineup against usual opponent MIT. On January 8 Harvard played only the second game in the program's history against a western opponent when they faced Michigan Tech. The game was a debacle for the visitors as Harvard won 11–0 and looked well on their way to giving Yale a run for the intercollegiate championship. After another win over Boston University, Harvard welcomed Marquette to the Boston Garden on February 5 but the three-week layoff since their previous game appeared to have the Crimson champing at the bit. Harvard took 10 penalties during the game, giving Marquette two separate 5-on-3 advantages. The Crimson defense responded well, holding back the Hilltoppers through most of the game, but Marquette slowly built a 2–1 lead and carried into the third period. With only 5 minutes remaining both teams began a furious effort to score and four goals were made at the end of the game, however, Harvard couldn't catch Marquette and lost 3–4. Harvard had their two series against Dartmouth and Yale remaining and redoubled their defensive efforts for the contests. In the two games against the Indians Harvard surrendered just one goal and then had a two week wait for the showdown with their arch rival. The Elis entered the series undefeated for the second year in a row and Harvard would have the honor
