Sanbon-dong is a "dong", or neighborhood, in Gunpo, a satellite city of Seoul in Gyeonggi Province, South Korea. Its total area is . Due to its population of more than 50,000, for administrative purposes the area is divided into two "dong", Sanbon 1-dong and Sanbon 2-dong. Its name can be translated as "the mountain's root," and refers to its position at the base of Surisan's eastern flank. On the other side of Surisan () lies Anyang City.
The administrative entity of Sanbon was formed in 1914, as part of a general nationwide consolidation of local government under the Japanese occupation. At that time it was Sanbon-"ri", a rural precinct of Siheung County. When it became part of the new Gunpo City in 1989, its status was changed from "ri" to "dong". The name is believed to derive from "Sanjeo", "low on the mountain," which was first used to describe the region in 1789.
