Southeast Borneo Federation (Indonesian: Federasi Kalimantan Tenggara) was an autonomous area formed in the southeastern part of Indonesian island of Borneo by the Netherlands in 1948 as part of an attempt to re-establish the colony of the Dutch East Indies during the Indonesian National Revolution. Southeast Borneo became a constituent part of the United States of Indonesia in 1949. The Federation was dissolved on 18 April 1950 and combined with Great Dayak and Bandjar to form South Kalimantan Province.
