The 1998–99 NCAA Division I men's ice hockey season began on October 3, 1998, and concluded with the 1999 NCAA Division I Men's Ice Hockey Tournament's championship game on April 3, 1999, at the Arrowhead Pond of Anaheim in Anaheim, California. This was the 52nd season in which an NCAA ice hockey championship was held and is the 105th year overall where an NCAA school fielded a team.

The Canisius Golden Griffins men's ice hockey team is a National Collegiate Athletic Association (NCAA) Division I college ice hockey program that represents Canisius University. The Golden Griffins are members of Atlantic Hockey America, formed shortly after the 2023–24 season by the merger of their former hockey league, the Atlantic Hockey Association, with College Hockey America. They play at the LECOM Harborcenter in Buffalo, New York across the street from KeyBank Center, home of the Buffalo Sabres of the National Hockey League. Canisius has won an automatic bid to the NCAA Men's Ice Hockey Tournament twice, after winning the Atlantic Hockey title in the conference playoffs in both 2013 and 2023, but lost in the first round to the top-ranked team each time.
