The Princeton Tigers represent Princeton University in ECAC women's ice hockey during the 2017–18 NCAA Division I women's ice hockey season. In the immediate aftermath of the successful 2016-17 campaign, Kelsey Koelzer signed a late season contract with the New York Riveters of the NWHL. Koelzer, who has since graduated, signed in time to bolster the Riveter's playoff roster. Following a bid to make the US National Team for the 2018 Olympics, Koelzer re-signed with New York (renamed the Metropolitan Riveters), for 2017–18.
