Dulovo (Bulgarian: Дулово [ˈduɫovo], Turkish: Akkadınlar, Romanian: Accadânlar) is a town in Silistra Province in northeastern Bulgaria, in the Ludogorie region.

As the administrative centre of the homonymous Dulovo Municipality, it is the third largest town in the province after Silistra and Tutrakan.

[1] Dulovo, then a village, was first mentioned in an Ottoman document of 1573 as "Akkadınlar", meaning "White Women".

Even before the Liberation of Bulgaria in 1878, it had a mixed population of Bulgarians (settlers from the region of Preslav) and Turks, which is still reflected in the ethnic composition today.

Following the Second Balkan War, Bulgaria was forced to cede it to Romania along with all of Southern Dobruja.
