The Bukharan People's Soviet Republic was a Soviet state that governed the former Emirate of Bukhara during the years immediately following the Russian Revolution. In 1924, its name was changed to the Bukharan Socialist Soviet Republic. After the redrawing of regional borders, its territory was assigned mostly to the Uzbek SSR and some to the Turkmen SSR.

The Emirate of Bukhara was a Muslim polity in Central Asia that existed from 1785 to 1920 in what is now Uzbekistan, Tajikistan, Turkmenistan and Kazakhstan. It occupied the land between the Amu Darya and Syr Darya rivers, known formerly as Transoxiana. Its core territory was the fertile land along the lower Zarafshon river, and its urban centres were the ancient cities of Samarqand and the emirate's capital, Bukhara. It was contemporaneous with the Khanate of Khiva to the west, in Khwarazm, and the Khanate of Kokand to the east, in Fergana. In 1920, it ceased to exist with the establishment of the Bukharan People's Soviet Republic.
