The paper summarizes numerous scattered data on the former distribution of the Eurasian beaver in Bulgaria, many of them unpublished till now. Data on fossil, subfossil and subrecent records (Late Pleistocene to 19th century AD) from 43 localities situated in 19 of the total of 28 provinces, and 209 bone/teeth finds of at least 11 skeletal elements are presented. Geographical, altitudinal and chronological distribution as well as the representation of particular rivers and skeleton elements is presented and analyzed. About 56 percent of the sites were situated between 100 and 300 m. a. s. l. Five sites revealed Paleolithic occurrence, 20 Neolithic, 12 Chalcolithic, six Bronze Age, two Iron Age. The six subrecent sites are dated to the last 2000 years. The species distribution declined about and after the turn of BC/AD. The 43 localities were situated along 28 Bulgarian rivers. All finds are related to lowland areas and lower courses of the rivers. Evidence for the last record in the country is dated 1750–1850 AD.
