Southwestern High School is a public high school in Somerset, Kentucky. Operated by Pulaski County Schools, Southwestern opened its doors in the fall of 1993 to alleviate crowding at the district's other high school, Pulaski County High School. It is fed by several schools operated by the Pulaski County district, namely Nancy Elementary, Burnside Elementary, Southern Elementary, Oak Hill Elementary, and Southern Middle School. Students at Science Hill School, a K–8 school operated by a separate district within Pulaski County, have the option of attending either Southwestern or Pulaski County High.
