Toms River High School South is a comprehensive four-year public high school, and was the first high school established in Toms River (formerly Dover Township) in Ocean County, New Jersey, United States, serving students in ninth through [twelfth grade]]s as part of the Toms River Regional Schools. The original Toms River High School graduated its first class in 1891 and the current building opened for students in 1951. In 1969, when the high school was found to be too small, a second high school, Toms River High School North was opened and South was appended onto the school's original name, and a third high school in the district, Toms River High School East, was opened in 1979. The school day lasts six hours and 20 minutes.
