South Hills High School, often known by its abbreviation SHHS, is a public high school located in the hills of the eastern part of West Covina, California. There is a common misconception that it is in Covina, most likely because the school is in the Covina-Valley Unified School District rather than the West Covina Unified School District. South Hills opened in the fall of 1964.

The buildings were designed by architect Henry L. Gogerty (1894–1990) in the year 1963.

During the 1993–1994 school year, there were 1,306 students enrolled at the school. This has since grown, with 2,113 students enrolled during the 2007–2008 school year. Currently, enrollment stands at 1,650 students, of which 500 are transfer students on permit from other school districts.
