Budaörs (Hungarian: [ˈbudɒørʃ]; German: Wudersch; Croatian: Jerša, Erša or Vundeš; Latin: Vicus Teuto) is a town in Pest County, Budapest metropolitan area, Hungary.

The first written mention of Örs dates from 1236 when Béla IV, king of Hungary donated a church together with the St. Martin chapel to the Cistercians.

Under the Turkish occupation during Ottoman rule the area was uninhabited and was resettled by Schwab peasants in the early 18th century by the countess Zsuzsanna Bercsényi.

World War I affected the town badly, and it was the scene of a short fight between Hungarian royalists and the government in the Battle of Budaörs on 23–24 October 1921.

After World War II, it was at Budaörs where the Communist government begun forcing ethnic Germans to leave their homes.
