Oybin (Upper Sorbian: Ojbin, pronounced [ˈɔjbʲin]) is a municipality in the Görlitz district, in Saxony, Germany, located very close to the border of the Czech Republic.

Following the defeat of the Protestant armies by the Habsburgs in the Battle of the White Mountain in 1620, many Protestant Czechs found refuge across the border in the hills of Upper Lusatia.

It is a "Kurort", a resort or spa certified by the state, where people go for rest and recuperation.

It is most famous for its mountain of the same name, an exposed natural sandstone dome that towers above the town.

Many bizarrely shaped geological rock formations can be found in the surroundings.
