Sirishtnik (Bulgarian: Сирищник [ˈsiriʃtnik]) is a village in western Bulgaria, part of Kovachevtsi municipality, Pernik Province.
It lies 25 km west of Pernik, at 42°34′N 22°49′E / 42.567°N 22.817°E / 42.567; 22.817, 742 metres above sea level.
The village is situated on the banks of the Svetlya River, a tributary of the Struma.
Sirishtnik is the birthplace of former Bulgarian President Georgi Parvanov, who, while born there, grew up in the neighbouring village of Kosacha, from where his mother and father stem.
The locals tie the name to the well-developed in the past animal husbandry and cheese (sir or sirene) production, but this is perceived as folk etymology due to the loss of the word's original meaning.
