The Mačva War of 1268 was a brief conflict in the Duchy of Mačva (or Macsó), in the southern realm of the medieval Kingdom of Hungary. Taking advantage of the internal conflict and its consequences in Hungary, Stefan Uroš I brought an invasion force to Mačva, and did considerable damage to the city and the province until Hungarian reinforcements under Béla IV from the north came to fight off the Serbs. This turned the tide of the conflict, and Stefan Uroš was captured by the Hungarians, and Hungary retained the city, albeit with heavy losses.

Mačva was not to stay in Hungarian hands for much longer, however, for in 1284, Stefan Dragutin of Serbia married Catherine of Hungary, and received Mačva from King Ladislaus IV.
