Pirin Macedonia or Bulgarian Macedonia[Note 1] (Bulgarian: Пиринска Македония; Българска Македония) (Pirinska Makedoniya or Bulgarska Makedoniya) is the third-biggest part of the geographical region of Macedonia, today in southwestern Bulgaria. This region coincides with the borders of the Blagoevgrad Province, as well as the surrounding area of Barakovo from the Kyustendil Province. After World War I, Strumica and the surrounding area were broken away from the region and were ceded to Yugoslavia.
It covers an area of about 6,798 km2, which is 10.18% of the geographical region of Macedonia. One of the regional centers is Blagoevgrad. The region is bordering with Kyustendil Province and Sofia Province to the north, Pazardzhik Province and Smolyan Province to the east, Greece to the south and North Macedonia to the west. The population is estimated around 325,000 people. [citation needed]
