Wonder Works is a children's museum, a non-profit corporation established in 2002, located in the village of Oak Park, Illinois.

The museum is dedicated to the principle of offering a fun, largely self-directed playing and learning place for children.

Occupying its own building in one of the village's business districts, the museum attracted seventy thousand visitors in 2017.

They enjoyed the facilities as drop-in visitors, as museum members, as birthday party invitees, or as special-event attendees.

The museum funds its operations by means of the sale of visitor day passes, yearly memberships, proceeds from special events, and fundraising.
