The 2017 IIHF Women's World Championship Division I consisted of two international ice hockey tournaments organized by the International Ice Hockey Federation. Division I A and Division I B represent the second and third tier of the IIHF Women's World Championship.
At the 2017 IIHF annual congress it was decided that the Top Division would expand from eight to ten teams. As a result, all relegations from the 2017 tournaments were cancelled, and there would also be no relegation in all 2018 tournaments.
The Division I Group A tournament was played in Graz, Austria, from 15 to 21 April 2017.
4 referees and 7 linesmen were selected for the tournament.
