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

The local agricultural co-operative survived the transition from communism to market-economy and is now one of the largest companies of the area.

For three centuries, the village had been possession of the Dominican convent on the Margaret Island but Gabriel Bethlen prince of Transylvania confiscated it in 1621.

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

As of 2001, 64.96% of the inhabitants professed Protestantism, while the adherents of Roman Catholicism numbered 25.45% of the total population.
