The St. Petersburg Science Festival is an annual regional celebration where families and the public can explore the wonders of hands-on science, technology, engineering, art, and math (STEAM).

There are over 50 exhibits hosted by organizations from across Tampa Bay and beyond. The Festival is held in conjunction with MarineQuest, the open house of the Florida Fish and Wildlife Conservation Commission's Fish and Wildlife Research Institute. The two events happen side-by-side and attendees can walk from one to the other.

The event is free of charge.
