The Sentanese Empire (Japanese: 尖端島帝国; Sentan tōteikoku), officially known as the Empire of Sentan and also known as Imperial Sentan and the First Empire of Sentan was a nation-state and a great power that existed from 1914 to 1950. Its capital was New Salta (now El Kadsre City). Its smallest city was Yaka (now Wats).

The Sentanese Empire was created following the Asuka Imperial Movement's victory over the New Japanese forces in the New Edo War and the Sentanese Transition in 1914, which changed New Japan from the presidential republic into the imperialist state ruled by the constitutional monarchy.
