The Kresna–Razlog Uprising (Bulgarian: Кресненско-Разложко въстание, Kresnensko-Razlozhko vastanie) was a Bulgarian uprising against the Ottoman rule, predominantly in the areas of Kresna and Razlog in late 1878 and early 1879. It broke out following the protests and spontaneous opposition to the decisions of the Congress of Berlin, which, instead of ceding the Bulgarian-populated parts of Macedonia to the newly reestablished Bulgarian suzerain state per the Treaty of San Stefano, returned them to Ottoman control. It was prepared by the "Edinstvo" Committee.
