2018 IIHF World Women's U18 Championship Division I

The 2018 IIHF World Women's U18 Championship Division I was three international under-18 women's ice hockey tournaments organized by the International Ice Hockey Federation (IIHF). Divisions I A, I B and I B Q represented the second, third and fourth tier of competition at the 2018 IIHF World Women's U18 Championship.

Division I Group A
The Group A tournament was held in Asiago, Italy from 8 to 14 January 2018. Having just been relegated to Division I in 2017, Japan entered the tournament with something to prove, handily winning all five matches in regulation and reclaiming their place in the Top Division. Despite eking out a shootout win against Hungary, Norway amassed the fewest points and were relegated to Division I Group B.
