The Colony of Aden or Aden Colony (Arabic: مستعمرة عدن‎ Musta‘marat ‘Adan) was a British Crown colony from 1937 to 1963 located in the south of contemporary Yemen. It consisted of the port of Aden and its immediate surroundings (an area of 192 km2 (74 sq mi)). Prior to 1937, Aden had been governed as part of British India (originally as the Aden Settlement subordinate to the Bombay Presidency, and then as a Chief Commissioner's province).
