Marburg's Bloody Sunday (German: Marburger Blutsonntag,Slovene: Mariborska krvava nedelja) is the name of a massacre that took place on Monday, 27 January 1919 in the city of Maribor (German: Marburg an der Drau) in Slovenia. Soldiers from the army of the Kingdom of Serbs, Croats and Slovenes (later Yugoslavia), under the command of Slovene officer Rudolf Maister, killed between 9 and 13 civilians of German ethnic origin, wounding a further 60, during a protest in a city centre square. Estimates of casualties differ between Slovene and Austrian sources.

In November 1918, after the First World War ended, the territories of southern Carinthia and southern Styria, which had been claimed by the Republic of German Austria, were captured by military units under Maister's command.

Maribor was the largest city of southern Styria, and had a predominately German population. A US delegation led by Sherman Miles visited Maribor on 27 January 1919 as part of a wider mission to resolve territorial disputes. On the same day, German citizens organised a protest proclaiming their desire for Maribor to be incorporated into the Republic of German Austria. The protest was interrupted by Meister's soldiers firing at the people and causing numerous casualties. In response, German Austria launched a military offensive which expelled the Yugoslavs from several small towns in Upper Styria along the Mur River. A ceasefire was agreed under the mediation of France in February 1919. According to the Treaty of Saint-Germain-en-Laye, signed on 10 September 1919, Maribor and the rest of Lower Styria became part of the Kingdom of Serbs, Croats and Slovenes. No-one was ever charged over the Maribor massacre.
