Summerville High School is a public high school in Summerville, South Carolina.
 Until the 1960s, a brick building on Main Street, which was once Rollings Middle School of the Arts, and now is the district building for all schools in the Dorchester area, was the only high school in the Summerville area. As Summerville's population increased rapidly in the late 1960s and early 1970s, a larger campus was needed. In 1969, the present building on Boone Hill Road was opened to students. From the first day of classes, the new facility was too small. Because of the unexpectedly high enrollment, several mobile units were set up on the campus.
 In 1970, Summerville High School and Alston High School were combined to integrate the school district. Attendance continued to increase throughout the 1970s. In 1972, double sessions were used until an additional underclassman campus was completed in 1975. Another classroom wing was created by the spring of 1978.
 In 1992, Fort Dorchester High School was opened, splitting the school's student body. As a result, the Gregg underclassman campus was renovated as a middle school, and the switch to a single campus was completed in 1998. Construction of a fine arts hall and cafeteria expansion was completed in the fall of 2001.
 In 2008, Ashley Ridge High School was opened to further ease congestion in the Dorchester District Two school system. When attendance zones were realigned for the opening of the new high school, the Ashley Ridge zone contained mostly students who would have attended Summerville high school, whereas only a small portion of the Fort Dorchester attendance zone was diverted.
 As of 2004, Summerville has a 78.9% graduation rate. However, the school boasts a 97.3% passing rate of the state's standardized exit exam.
