Outside Streetball Festival takes over The Refinery on April, 4th 2026! Featuring a 3V3 tournament, dunk contests, live art installations, local vendors, and headlined by Nappy Roots, this is not an event to miss.  Outside Streetball Festival is Charleston's first streetball, music, and arts festival. It's bigger than basketball.  Born from a journey chasing courts around the world, Outside brings that global street energy home. This is where hoops, music, and art meet the energy of the city in one full-out celebration. Outside is for anyone who sees the world as a canvas, or a court. Whether you're here to play, peform, or just enjoy a unique experience, Outside Streetball Festival is for you.
