Kosovo, where ethnic Albanians make up 90 per cent of the 1.8 million population, declared independence from Serbia on February 17.
Kosovo has been recognised by around 40 countries, including the US and most European Union nations, since its declaration.
UN and ethnic Albanian leaders are concerned that Belgrade may use the polls to strengthen a parallel Serbian administration at the local level.
Such a structure has remained since the 1999 war in the area, thanks to Serbia's political and financial assistance.
Leaders of the Kosovo Albanian government and Unmik have said that the local elections are illegal and that they will simply ignore the vote.
Speaking last week, Hajredin Kuci, Kosovo's deputy prime minister, said: "The Serbian elections are not legal and legitimate. But the government won't use any violence to stop them."
