Oltre Giuba or Trans-Juba (Arabic: شرق جوبا الإيطالية) was an Italian colony in the territory of Jubaland in present-day southern Somalia.

[2] The territory thereafter had a brief existence as Trans-Juba (Oltre Giuba) under governor Corrado Zoli (16 July 1924–31 December 1926).

Britain retained control of the southern half of the partitioned Jubaland territory, which was later called the Northern Frontier District.

During this period, the city was the third largest in Somalia and served as a port of call for small military ships.

The Bajuni Islands ("Isole Giuba") were part of British East Africa until World War I.
