Király Bath or Király fürdő is a thermal bath that was first built in Hungary in the second half of the sixteenth century, during the time of Ottoman rule. The bath and its neighborhood have since become part of the consolidated city of Budapest.

It still retains many of the key elements of a Turkish bath, exemplified by its Turkish dome and octagonal pool. It is located at the corner of Fő utca and Ganz utca. Its address and entrance is Fő utca 82-84 (green façade on the pictures linked to below) while the exterior of the bath proper is on Ganz utca (domed stone structure, ibidem).

Components of thermal water include sodium, calcium, magnesium bicarbonate, sulphate-chloride and a significant amount of fluoride ion. The water temperature in the four different pools have some difference, but in between 26-40 ℃.

The Király Baths are open to both sexes.
