Vlčany (Hungarian: Vágfarkasd) is a village and municipality in Šaľa District, in the Nitra Region of south-west Slovakia.

The village lies at an altitude of 112 metres and covers an area of 39.764 km².

After the Austro-Hungarian army disintegrated in November 1918, Czechoslovak troops occupied the area, later acknowledged internationally by the Treaty of Trianon.

Between 1938 and 1945 Vlčany once more became part of Miklós Horthy's Hungary through the First Vienna Award.

The town has its own birth registry office and police force covering the municipality.
