The 2023–24 Dartmouth Big Green Men's ice hockey season was the 117th season of play for the program and the 62nd in ECAC Hockey. The Big Green represented Dartmouth College, played their home games at the Thompson Arena and were coached by Reid Cashman in his 3rd season.

Dartmouth started the year in a rather peculiar position. Though a relatively low-scoring team, the Big Green saw a vast improvement by their defense and, perhaps more importantly, their starting goaltender Cooper Black. Inasmuch, the team found it difficult to win games but they refused to surrender to their opponents. In the first 11 games of the year, Dartmouth tied more than half and went into the winter break as a relative unknown.

The team returned with the annual Ledyard Bank Classic but the time off appeared to have softened the defense. Dartmouth went 2–4 coming out of the break and appeared to be heading towards another losing season. In late January, however, things began to change. Sophomore Luke Haymes, who had been one of the better forwards already, caught fire. Beginning with the match against Rensselaer on January 20, he ran roughshod over ECAC defenses and scored 24 points (14 goals 10 assists) in the final 12 games of the regular season. His offensive explosion helped turn Dartmouth's season around and allowed the Big Green to go 7–2–3 down the stretch. Dartmouth climbed their way up the conference standings and finished 1 point ahead of Clarkson for 4th place.

The streak not only gave the team home ice but provided the Greens with a bye into the quarterfinal round. The week off appeared to end Haymes' hot streak but the rest of the team picked up the pace and ensured that Dartmouth had enough scoring to dispatch Union in straight sets. In the semifinals, Dartmouth met Cornell and looked to have the measure of the Big Red for the first two periods. The Big Green had a 3–1 lead with 20 minutes to play but had to kill off a penalty at the start of the period. Unfortunately, Cornell was able to convert on their only man-advantage of the match and that goal seemed to spark the Reds. Cornell scored two more goals in the middle of the period to take the lead and then held off Dartmouth with their stingy defense. In desperation, Cooper Black was pulled for an extra attacker but that only allowed Cornell to score twice into an empty net to turn the match into a rout.^[1]

Despite the collapse at the end, Dartmouth had finished the year with a winning record for the first time in eight years and posted a dramatic turnaround going from 12th to 4th in the conference standings.
