Siheung County, alternatively Shihŭng County was a county (gun) in Gyeonggi Province, South Korea. This county was abolished in 1989 as its one town(읍) of Sorae and two townships(면) of Gunja and Suam became Siheung City at the same time. Today's Siheung City area did not belong to Siheung County before 1914. The area rather was part of old Incheon or Ansan.
