The House of Mrnjavčević (Serbian Cyrillic: Мрњавчевић, pl. Mrnjavčevići / Мрњавчевићи, pronounced [mr̩̂ɲaːʋt͡ʃeʋit͡ɕ]) was a medieval Serbian noble house during the Serbian Empire, its fall, and the subsequent years when it held a region of present-day Macedonia region. The house ruled a province from its base at Prilep (in modern North Macedonia) from 1366 to 1395.

Vukašin Mrnjavčević was a military commander in the army of Emperor Dušan the Mighty (r. 1331-1355) and co-ruler of Serbia as king, with Emperor Uroš the Weak (r. 1355-1371). After Uroš' death, the Serbian Empire crumbled, as the nobility could not agree on its rightful successor. Vukašin's son, Marko Kraljević, ruled his hereditary lands as titular King of Serbs and Greeks.
