Turckheim (French pronunciation: [tyʁkaim] ⓘ; Alsatian: Tercka; German: Türkheim) is a commune in the Haut-Rhin department in Grand Est in north-eastern France.

When the Germanic tribes invaded and crossed the Rhine, the Thuringii settled here and possibly gave their name to the town, which was first Thorencohaime and then Thuringheim.

After the Peace of Westphalia (1648), Turckheim and the other Alsatian towns refused to swear allegiance to the French king.

[citation needed] In 1871, at the end of the Franco-Prussian War, the town, with the rest of the Alsace, became part of the German Empire.

[citation needed] Turckheim is one of only a few remaining towns in France with a municipal night watchman, who makes the rounds at 10 p.m. between 1 May and 31 October and on the three Saturdays preceding Christmas.
