Greenville Technical Charter High School (GTCHS) is a small school located on the Barton Campus of Greenville Technical College in Greenville, South Carolina, United States. It is a middle college high school. It was established as the first charter school in South Carolina and in partnership with Greenville Technical College. It was the first charter school to be awarded the National Blue Ribbon of Excellence (2010) and the Palmetto's Finest Award (2008).

As part of the middle college program, students are encouraged to take college classes through Greenville Technical College for minimal fees; while the majority begin sophomore year, the Early College Cohort can begin as freshmen. Approximately 60% of students graduate from GTCHS with 24 or more college credits and GTCHS graduates high school students with Associate Degrees every year.

GTCHS was the first school in the state to pilot the AOPA Curriculum. This innovative career pathway leads to three possible outcomes: Pilot, Engineer, Aircraft Maintenance Technician.
