Topoľníky (Hungarian: Nyárasd, pronounced [ˈɲaːrɒʒd]) is a village and municipality in the Dunajská Streda District in the Trnava Region of south-west Slovakia.

Local tradition holds that the Mikóczy, Csölle, Nagy, Szalay, Várady, Tóth és Szabó families, millers and fishermen for profession, were the first settlers in the village.

Until the end of World War I, it was part of Hungary and fell within the Dunaszerdahely district of Pozsony County.

After Soviet occupation in 1945, Czechoslovak administration returned and the village became officially part of Czechoslovakia in 1947.

Its original Slovak name derived from the Hungarian form as Náražd, but it was Slovakised by the authorities to the current official name in 1948.
