About Us
Our Vision
Outside Streetball 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. We’re here to connect creators, competitors, and communities, from jaw-dropping dunks to live musical performances, bold murals, and great food.
Outside is for anyone who sees the world as a canvas - or a court. Whether you're here to play, perform, or just enjoy a unique experience, Outside Streetball Festival is for you.
