The Italian colonial empire (Impero coloniale italiano), also known as the Italian Empire (Impero italiano) between 1936 and 1941, was founded in Africa in the 19th century and it comprised the colonies, protectorates, concessions and dependencies of the Kingdom of Italy. In Africa, the colonial empire included the territories of present-day Libya, Eritrea, Somalia and Ethiopia (the last three being officially named "Africa Orientale Italiana", AOI); outside Africa, Italy possessed the Dodecanese Islands (following the Italo-Turkish War), Albania (1917–1920 and 1939–1943) and had some concessions in China, including in Tianjin.
The Fascist government that came to power under the leadership of the dictator Benito Mussolini after 1922 sought to increase the size of the Italian empire and it also sought to satisfy the claims of Italian irredentists. Systematic "demographic colonization" was encouraged by the government, and by 1939, Italian settlers numbered 120,000–150,000 in Italian Libya and 165,000 in Italian East Africa.
During World War II, Italy allied itself with Nazi Germany in 1940 and it also occupied British Somaliland, western Egypt, much of Yugoslavia, Tunisia, parts of south-western France and most of Greece; however, it then lost those conquests and its African colonies to the invading allied forces by 1943. In 1947, Italy officially relinquished claims on its former colonies. Only the territory of Somalia was eventually turned into a UN trust territory under Italian administration until 1960. Following the independence of Somalia in 1960, Italy's 65-year period of imperialism concluded.

Imperialism in Italy dates back to ancient Rome, and the Latin notion of mare nostrum ("Our Sea", referring to the Mediterranean) has historically been the basis for Italian imperialism, especially during the fascist era. During the Middle Ages and the modern period, the Republic of Venice and the Republic of Genoa controlled networks of "colonies" in the Mediterranean region known as the Venetian Empire and the Genoese Empire respectively.
