The FIVB Volleyball Women's U21 World Championship is the world championship of volleyball for female players under the age of 21 organized by Fédération Internationale de Volleyball (FIVB).

The most recent tournament was jointly hosted by Netherlands and Belgium and won by Italy.

In March 2022, FIVB decides to change the age category of the tournament by moving it from U20 to U21 in order to equate it with the Men's U21 World Championship.

A corresponding tournament for male players is the FIVB Volleyball Men's U21 World Championship.
