Vazovo (Bulgarian: Вазово, formerly Ески Балабанлар, Turkish: Eski Balabanlar) is a village in northeastern Bulgaria, part of the Isperih Municipality of Razgrad Province, located in the central part of the Ludogorie region.

The lower end of the village (located west of today's Municipal building) was called Kasim Kuyucuk until 1931 and later Rakovski as a result of Bulgarian Communist Party's assimilation policy.

Until 1931 the upper end of the village (located east of the Municipal building) was called Zincirli Kuyucuk and later Kladentsi.

In the 1980s Rakovski enjoyed a financial and civic prosperity when the majority of the working adults were employed by the glass factory Dianko Stefanov.

In mid-1980s the school's soccer/football team whose players are generally 7th or 8th graders became province (okrazhni) champions two years in a row and move into regional competition with the teams of Trustenik (Ruse) and Sokol (Silistra).
