The Brsjak Revolt (Serbian Cyrillic: Брсјачка буна, Brsjačka buna) was an uprising in 1880-1881, in areas of Demir Hisar, Poreče and Kičevo in present-day Macedonia. The leaders of the uprising were local Chetnik: Ilija Delija, Rista Kostadinovich, Micko Krstich and Andjelko Tanasovich.
After the Serbo-Turkish war in 1876-78, the assembling of 65 of the most notable men of the districts of Kumanovo, Kriva Palanka, Kočani, Štip, Veles, Prilep, Bitola, Ohrid, Kičevo and Skopje sent an appeal to the Serbian commander of Macedonian volunteers (Serbo-Turkish war) M.S. Milojevic, asking for the arming and leading towards an insurrection.
In 1880, the populations of the counties Kičevo, Poreče, Bitola and Prilep engaged in a 6-month long uprising that ended in failure.
