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

The vineyard in its territory was already mentioned in 1205, but the village itself was first recorded in 1296 when Andrew III of Hungary donated an estate to a certain Chunt.

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

The territory of the village was partitioned between Vojka nad Dunajom and Rohovce in 1988, but became an independent municipality again in 1993 following a referendum.

Roman Catholicism is the majority religion of the village, its adherents numbering 95.12% of the total population.
