The lira AOI was a special banknote circulating in Italian East Africa (Africa Orientale Italiana, or AOI) between 1938 and 1941.
In 1938, banknotes were issued for use in Italian East Africa in denominations of 50, 100, 500 and 1000 lire. The designs were the same as those used on Italian notes but the colours of the notes were different and they bore an overprint with the words "Serie Speciale Africa Orientale Italiana". The lira AOI was replaced by the East African shilling in 1941, when the United Kingdom gained control of Italy's colonies, at the rate of 1 shilling = 24 lire. The banknotes retired by the British government were later used by the British Army when it occupied Italy between 1943 and 1945, producing with the AM-lira a high inflation in the country.
