Simpang Empat is a district of Karo Regency in North Sumatra.
It borders Kabanjahe and Berastagi districts to the east, Payung to the west, Naman Teran and Merdeka to the north and Kabanjahe district to the south.
Prior to independence, Simpang Empat was ruled by the Karo king Sibayak of Lingga, whose domain consisted of the subkingdoms of Sitelu (ruled by a king of marga Karo-Karo), Tigapancur (ruled by a king of marga Sembiring Gurukinayan), and Siempat Teran (ruled by the king of marga Karo-Karo Sitepu). The district is called Simpang Empat because the government building was constructed at the intersection (Simpang) where the three kings once met.
