The Emirate of Bukhara (; ) was a Central Asian state that existed from 1785 to 1920. It occupied the land between the Amu Darya and Syr Darya rivers, known formerly as Transoxiana. Its core territory was the land along the lower Zarafshan River, and its urban centres were the ancient cities of Samarkand and the emirate's capital, Bukhara. It was contemporaneous with the Khanate of Khiva to the west, in Khwarezm, and the Khanate of Kokand to the east, in Fergana. It is now within the boundaries of Uzbekistan.
