Slobozia is a city in Romania and the capital of Ialomița County, in the historical region of Muntenia. It lies in the southern part of the country, in the Bărăgan Plain, a flat agricultural area between Bucharest and the Danube.
At the 2021 census the city had a population of 41,550. As a county capital, it serves as the administrative centre for Ialomița County, hosting its local government institutions.
Slobozia is connected to other parts of Romania by road and rail, and its position on the Bărăgan Plain places it within a predominantly farming landscape. The city is not to be confused with other Romanian localities of the same name.
