The Porter-Gaud School is an independent coeducational college preparatory day school in Charleston, in the U.S. state of South Carolina. Porter-Gaud has an enrollment of some 1000 students, comprising an elementary school, middle school, and high school, and is located on the banks of the Ashley River. The school has historic ties to the Episcopal Church. In May 2008, Porter-Gaud acquired The O'Quinn Schools, a local preschool that dates back to the early 1970s, with the intention of maintaining the names of the schools, faculties, programs, and tuition policies.
