Early years Dartmouth College fielded their first ice hockey team in January 1906, winning their first game 4–3. The team played an expanded schedule the next two years but after a 1–5–1 finish in 1908 the program hired its first head coach and promptly posted a 10–3–1 record. The ice hockey club would bring in a new bench boss each year until 1912 when
Fred Rocque stayed for three seasons followed by
Clarence Wanamaker with four. Dartmouth was able to win more than they lost during this time despite the coaching turnover and the lack of local facilities. The team played precious few games at home, hosting a total of 16 over 13 seasons. In 1918 the university decided to suspend the program as a result of the ongoing
first World War but returned in January 1920 and had continued unabated ever since. The next season Bill Riley led the nation in scoring, posting 41 assists and 78 points, setting season- and career-best marks for Dartmouth while his brother tied the team record for goals in one season with 45. Dartmouth slipped a bit in the standings, finishing 16–5 during the season but they returned to the tournament along with the same three teams from the year before. The Indians were given a change to avenge their loss from the year before and took advantage by dropping the powerhouse Wolverines 4–2 and reached their second championship game. Over the course of the season
Boston College had lost only one game and that was to Dartmouth. The Indians played the Eagles close, taking a 2–1 lead into the second period after Bill Riley scored with less than a minute remaining in the first. BC responded with two quick goals in the second and the held the Indians off the board until the third. Shortly after Alan Kerivan tied the game the Eagles got their fourth goals of the night and held on to win the game. Once again, despite losing the championship, a Dartmouth player was named as tournament MOP, this time the award went to
Dick Desmond, another future member of the US hockey hall of fame as well as a
silver medalist at the
1952 Winter Olympics. After two consecutive runs in the NCAA tournament Dartmouth sharply declined. The team spent the next decade posting middling-to-bad records but this did not prevent Jeremiah from receiving the first
Spencer Penrose Award in
1951. The Indians posted a good record in
1959, going 17–8 but were edged out for the NCAA tournament by teams with better records. The following year Dartmouth had the best winning percentage of any eastern team (.725) and were one of four eastern teams selected for two play-in games (the only time this happened in NCAA tournament history) where they lost to
Boston University and them promptly declined in the succeeding years. Two years later Dartmouth was one of 28 teams that founded
ECAC Hockey but the change did little to improve their fortunes. Jeremiah took the
1964 season off and his assistant
Abner Oakes took over, leading the team to a 14–7 record, good enough for 6th in the conference but were snubbed by the ECAC selection committee and left out of the 8-team tournament. Once Jeremiah returned and the weakest dozen teams were removed from the conference, Dartmouth posted another good record, finishing 14–9 and this time they were invited to the
ECAC tournament but lost to eventual champion BC in the quarterfinals. Over the next two seasons the Indians won only 9 games but Jeremiah was award the Spencer Penrose Award for the second time in 1967. After that year Jeremiah resigned as head coach due to ill health and then died from cancer three months later.
Return to the NCAA Tournament Oakes coached the team for three years after Jeremiah's departure before turning the program over to
Grant Standbrook. The Indians were able to produce three good years under Standbrook and made their second ECAC tournament in
1974 but again could not get out of the quarterfinals. That year the university changed the team nickname to the Big Green after several years of pressure to move away from their unofficial 'Indians' moniker. Standbrook would coach one more season, ending on a sour note, before Dartmouth moved on to
George Crowe. The Big Green opened the season with their new head coach in a new home building, the
Rupert C. Thompson Arena. In their new digs the Big Green improved markedly, rising to 16 wins in Crow's first year and returned to the ECAC tournament. After two modest seasons, one in which the team began sponsoring a holiday tournament, the
Auld Lang Syne Classic, Dartmouth rose to 4th in the conference and won 19 games for the first time since
1948 and made their first ECAC championship game. Though the team lost the conference title tilt they were given the second eastern seed and returned to the
tournament for the first time in 30 years. Dartmouth opened against the
WCHA champion
North Dakota and lost a close game to the western champion 4–2 ben then redeemed themselves slightly with a consolation game victory. The following year the ECAC split their conference into three divisions and Dartmouth became the first Ivy Region champion. The Big Green rode their division title back to the ECAC title match, losing to fellow Ivy team
Cornell and getting the second eastern seed for the second consecutive year. Dartmouth found themselves in a rematch with the Fighting Sioux but the results were much the same with North Dakota winning 4–1. Once more Crowe's team won the consolation match to at least get something out of their tournament appearance but after 1980 the Big Green slid down the standings.
Decline to the bottom Crowe coached Dartmouth for four more years and could not post a winning record.
Brian Mason was brought in 1984, fresh off of two fantastic years with
Division II RIT, but he could not replicate his success at the
Division I level. In six seasons Mason's teams topped out at 10 wins and finished with losing records every year. They never finished better than 9th in the 12-team conference (after several former members left in 1984 to form
Hockey East) and consequently never made an appearance in the ECAC tournament. Mason was fired in 1990 and his assistant
Jeff Kosak was hired but after 10 days he resigned, citing 'personal and family reasons'. Dartmouth was eventually able to get
Ben Smith to serve as head coach for the
1990–91 season but after posting a program-worst 1–24–3 record he left to take over at
Northeastern. Smith's replacement,
Roger Demment, was able to improve the team's record but not by much. Over the next six seasons Dartmouth remained below .500 but was able to make the ECAC tournament twice, through they lost both games they played.
Gaudet Years In 1997 Dartmouth hired
Bob Gaudet away from
Brown, giving the program the first Dartmouth alumnus to helm the team since Oakes in 1970. The first three years under the new bench boss were much of the same but in Gaudet's fourth season the Big Green finally posted a winning season and won an ECAC tournament game both for the first time since 1980, ending a 21-year period of futility. The Big Green would record winning seasons over seven straight campaigns, twice winning 20 games (for the first time since 1948) and shared the ECAC regular season title in
2005–06, their first conference title in team history. Despite the championship Dartmouth was left out of the NCAA tournament after losing to
Harvard in the ECAC semifinal with a 10–1 debacle. Dartmouth continued to play well under Gaudet who became the team's all-time leader in victories in 2018, but the Big Green did not win a conference semifinal game during his tenure nor made an NCAA tournament appearance since
1980.
Reid Cashman On April 24, 2020, Bob Gaudet announced his retirement. His replacement,
Reid Cashman, was named Big Green coach on June 1, 2020. Jason Tapp was added as new Associate head coach on June 23, and assistant coach
Stavros Paskaris was added to the staff on July 6. Paskaris' stay was brief, as he left for Bowling Green in May, 2021. Troy Thibodeau joined the Big Green coaching staff from the USHL's Tri City Storm in June, 2021.
Championships Dartmouth won its first ECAC tournament championship on Saturday, March 21, 2026, defeating Princeton 2-1 in overtime. Sophomore Tim Busconi scored the winning goal. Junior goalie Emmett Croteau was crowned MVP. The team won the
ECAC regular season crown in 2006 and the
Ivy League title 15 times (1934, 1943, 1943, 1944, 1945, 1946, 1957, 1948, 1949, 1959, 1960, 1964, 1979, 1980 & 2007). ==Season-by-season results==
