The women's 30 kilometre classical cross-country skiing competition at the 2018 Winter Olympics was held on 25 February 2018 at 15:15 KST at the Alpensia Cross-Country Skiing Centre in Pyeongchang, South Korea.

Athletes qualified for this event by having met the A qualification standard, which meant having 100 or less FIS Points in the distance classification.

Countries received additional quotas by having athletes ranked in the top 30 of the FIS Olympics Points list (two per gender maximum, overall across all events).

Countries also received an additional quota (one per gender maximum) if an athlete was ranked in the top 300 of the FIS Olympics Points list.
