Fancy Nancy is a 2005 children's picture book series written by Jane O'Connor and illustrated by Robin Preiss Glasser.

Its first book entry spent nearly 100 weeks on the New York Times Best Seller list,[1] resulting in the launch of a series that now spawns over 100 titles, with sales of more than 50 million volumes.

On March 27, 2015, Disney Junior signed for the rights to create an animated television series starring Fancy Nancy, which premiered on July 13, 2018.

Fancy Nancy has spawned a line of toys and games focusing on dress-up and role play targeted towards preschoolers and children aged 5 to 7.

In addition, the Fancy Nancy brand includes licenses for clothing, paper party goods, crafts, and more.

Numerous bookstores and libraries around the United States have hosted events including readings by both Jane O'Connor and Robin Preiss Glasser, costume contests, "Fancy Nancy" days and tea parties.
