2009–10 Colgate Raiders women's ice hockey season

The Colgate Raiders represented Colgate University in the 2009–10 NCAA Division I women's ice hockey season. They would end up a disappointing 12-20-4 despite having 19 wins in the previous season, not being able to overcome a dreadful 1-7-1 start (they would go 11-11-3 for the rest of the regular season). 2009-2010 would be the beginning of a 5 year streak where they would fail to have a winning season, and it would not be until the 2017-2018 season that they would make the NCAA tournament.
