Szentgotthárd (German: St. Gotthard; Slovene: Monošter) is the westernmost town of Hungary. It is situated on the Rába River near the Austrian border, and is home to much of Hungary's small Slovene ethnic minority.
The town took its name from, and grew up round, the Cistercian Szentgotthárd Abbey, founded here in 1183.
In 1664, it was the site of the Battle of Saint Gotthard, where an Austrian army led by Raimondo Montecuccoli defeated the Ottoman Empire so that the Turks had to agree to the Peace of Vasvár, which held until 1683.
The town serves as the cultural centre of the Hungarian Slovenes.
