The Trust Territory of Somaliland, officially the "Trust Territory of Somaliland under Italian administration", was a United Nations Trust Territory situated in present-day Somalia. Its capital was Mogadishu and was administered by Italy from 1950 to 1960, following the dissolution of the former British Military Administration. It gained independence in 1960.

Somaliland, officially the State of Somaliland, was a short-lived independent country in the territory of the present-day unilaterally declared Republic of Somaliland, which regards itself as its legal successor. It existed on the territory of former British Somaliland for five days between 26 June 1960 and 1 July 1960, when it merged with the formerly Italian administered Trust Territory of Somaliland to form the Somali Republic.
