Studienka (formerly Slovak: Hasprunka, German: Hausbrunn or Haubsrun, Hungarian: Szentistvánkút, also mentioned as Iwanusfalua, Istvánfalva, Haszprunka, Szentistván, Poszony-Szentistván) is a town and municipality in western Slovakia in Malacky District in the Bratislava region.

Recent discoveries indicate that the first settlements date back to the so-called La Tène culture, where the present territory was inhabited by Celtic tribes.

The first written mention until recently was thought to be the last part of the three-volume work of Cities and Communities of Slovakia from 1592, where the municipality is registered under its German name Hausbrun.

In the 15th century, after the defeat of Kingdom of Hungary (1526–1867) to the Ottoman Empire in the Battle of Mohács in 1526, the area became part of the Habsburg monarchy.

The end of the war and the dissolution of Austria-Hungary in 1918 resulted in the outbreak of chaos in the village and subsequently looting, especially of wealthy Jewish population.

The names of the fallen soldiers are engraved on the memorial to the victims of the First World War from 1919, which stands in the park at St Stephen's Church.
