Slakovci (German: Zlaakowcz, Hungarian: Szlakóc) is a village in Stari Jankovci municipality of Vukovar-Syrmia County in eastern Croatia.

The village is connected with the rest of the country by the D46 state road connecting it with the town of Vinkovci and continuing into Serbia as the State Road 120 to the nearest town of Šid.

They got their name from the weed "slak" or the Hungarian word "slavok" which means Slavs.

The feudal family of Gorjanski built a fort in Slavkovci for defense against the Turks.
