Izmail Oblast (7 August 1940 — 15 February 1954) was an oblast in the Ukrainian SSR, roughly corresponding to the historical region of Budjak. It had a territory of 12400 km2. The oblast was organized on 7 August 1940 on the territory, known as Budjak or southern Bessarabia, occupied by the Soviet Union from Romania. It was originally known as Akkerman Oblast until 1 December 1940, i.e. before the oblast center was moved from Akkerman to Izmail. The oblast was administratively subdivided into 13 raions. On 15 February 1954, the oblast was liquidated, and its territory was included in Odesa Oblast. The current area is now divided into two municipalities (Izmail and Bilhorod-Dnistrovskyi) and nine raions; these cover 13188 km2 and in 2015 had a combined population of 592,842.
