Kukujevci (Serbian Cyrillic: Кукујевци) is a village located in the municipality of Šid, Srem District, Vojvodina, Serbia. As of 2011 census, it has a population of 1,955 inhabitants.
Prior to the Yugoslav Wars, the population of the village was 89% Croat. During the Yugoslav Wars and particularly as a spillover from the Croatian War of Independence local Croat community in Kukujevci was exposed to harassment and persecution by Serbian nationalists leading to community's expulsion from the village. As a consequence of the war demographic structure of the village is today almost entirely different with 90% of population being ethnic Serbs, mostly Serb refugees who left after the collapse of the self-proclaimed SAO Western Slavonia or from other parts of Croatia. The new Serbian population has sought to rename the village to Lazarevo.
