The women's 30 kilometre classical cross-country skiing competition at the 2010 Winter Olympics in Vancouver, Canada was held on 27 February at Whistler Olympic Park in Whistler, British Columbia at 11:45 PST.

The 30 kilometre has been skated as a mass start event at the World Championships since 2005 and since the 2006 Winter Olympics. Kateřina Neumannová of the Czech Republic was the defending Olympic champion though that event was held in the freestyle technique. She retired after the 2006-07 season and later chaired the organizing committee for the 2009 world championships. Poland's Justyna Kowalczyk, the defending Olympic bronze medalist, was the reigning world champion though that was also in the freestyle technique. The last World Cup event in the 30 km classical took place in Trondheim, Norway on 14 March 2009 and was won by Petra Majdič of Slovenia.
