2023–24 Clarkson Golden Knights men's ice hockey season

The 2023–24 Clarkson Golden Knights Men's ice hockey season was the 102nd season of play for the program and 63rd in ECAC Hockey. The Golden Knights represented Clarkson University in the 2023–24 NCAA Division I men's ice hockey season, played their home games at Cheel Arena and were coached by Casey Jones in his 13th season.

Season
Clarkson did not begin the year in good standing. After a decent result in the first week, the Golden Knights played inconsistently for the rest of October and ended up with a sub-.500 mark. The goaltending battle for the starting role was largely between two new players, freshman Emmett Croteau and senior Austin Roden. The later had gotten the job out of training camp but a lack of success early in the year gave the rookie a shot in goal. After a loss to Rensselaer to open the conference schedule, Roden was back in goal and he settled into the Knights' crease. Clarkson didn't lose another game the rest of the year and went into the winter break near the top of the ECAC standings.

When the team reconvened after Christmas, the Golden Knights were playing at the inaugural Adirondack Winter Invitational. They split their two games, both against ranked opponents, and finished third in the field. By that time, it was apparent that the team had no real chance of earning an at-large bud to the NCAA tournament as they sat 30th in the PairWise standings. While they still had a few games against ranked clubs left on their slate, the Knights could not afford to lose any of the remaining matches and in all likelihood have to win their tournament to return to the national tournament. Unfortunately, the scoring became inconsistent in January and split every weekend for the entire month. Roden, too, was unable to sustain a suitable level of play and he was spelled by Brady Parker in early 2024. Parker played marginally better at first but in early February, the bottom dropped out. Over a six-game stretch, the Golden Knights lost 5 games while averaging less than 2 goals per game. The bad stretch dropped the team down to .500 and put them in jeopardy of having to start their postseason in the first round.

Over the final three weeks, Roden turned in several key performances, including a pair of overtime wins against Cornell and Quinnipiac. However, the team still missed out on a bye into the quarterfinal round by 1 point. Clarkson started their playoff run against Rensselaer, the worst team in the standings. Despite being heavily favored in the game, the Knights didn't have energy in the first two periods and found themselves down entering the third. The team picked up the pace in the final 20 minutes but weren't able to get a marker on the board until the final 7 minutes of the match. After pulling Roden early, Mathieu Gosselin scored his team-leading 11th goal of the season and the Knights found themselves down by just 1 with more than two minutes to play. The shots came fast and furious in the final moments but Clarkson was unable to get the tying goal and saw their season end in a rather dismal fashion.
