Established in 1990, Pika's Festival is the most popular event in organised by Velenje Urban Municipality and the largest children's festival in Slovenia. Although planned from the outset as an event for children, it is also popular with parents and teachers.

The festival is named after heroine Pippi Longstocking (Swedish Pippi Langstrump, Slovene Pika Nogavička), a fictional character in a series of children's books created by author Astrid Lindgren. The spirit of Pippi/Pika as an unconventional and extraordinary strong heroine pervades the festival in Velenje, which aims to develop the imaginations of children as well as adults. Humanity and tolerance towards diversity and otherness is encouraged. The educational component of the project relates to culture as well as ecology, ethnology, anthropology, new media and technologies.

Pika's Festival is supported by Velenje Urban Municipality but also generates income through donations, sponsorship, grants and sales.
