The District of Peja (Albanian: Rajoni i Pejës, Serbian: Пећки округ, romanized: Pećki okrug) is one of the seven districts of Kosovo. It has its seat in the city of Peja. The district has three municipalities and 118 other settlements. According to the 2024 census, the district had 146,301 inhabitants, and is the least populated of all the districts of Kosovo.
In medieval times, the city was under Byzantine, Bulgarian and Serbian rule. After its integration into Serbian territory, it became the seat of the Serbian Orthodox Church in 1346. The Patriarchal monastery of Peć is a UNESCOWorld Heritage Site as part of the Medieval Monuments in Kosovo. Under Ottoman rule the city became a district capital with mosques and civil architecture. From the end of the nineteenth century until today, the city has been the site of nationalist aspirations and claims for both ethnic Albanians and Serbs, often resulting in tense inter-ethnic relations and conflict.
