Bad Tatzmannsdorf (Hungarian: Tarcsafürdő, Croatian: Tarča) is a municipality in Burgenland in the district of Oberwart in Austria.

Devastated by the Turks in 1529 and 1532, the town was subsequently settled by Croats in 1572 under the leadership of Gregor Tarrody, and later acquired by the Batthyany family in 1633.

Bad Tatzmannsdorf gained recognition as a health spa in the Regensberger History (Chronik) of 1621.

During the first half of the 1800s and beyond, it became a popular destination for visitors from Vienna, as mentioned by Adelbert Stifter in his novels.

The resort area now boasts a variety of world-class hotels, museums, sports complexes, and more.
