The South Carolina Science Olympiad Competition, often abbreviated as SCSO, is an annual Science Olympiad competition comprising middle school and high school teams across South Carolina. The competition was first held in the C Division (grades 9–12) in 1985, with the inaugural state champions being Irmo High School from Irmo. Bell Street Middle School from Clinton won the first B Division (grades 6–9) state championship a year later. The winners of the tournament represent South Carolina at the Science Olympiad National Tournament, held in May at various universities across the nation.
