Nötsch im Gailtal (Slovene: Čajna) is a market town in the district of Villach-Land in the Austrian state of Carinthia.

The settlement in the Duchy of Carinthia was first mentioned in a 1253 deed together with Lewenburg castle, present-day Wasserleonburg, then a fief of the Prince-Bishops of Bamberg.

During a series of ownership of several Villach merchant families, it was significantly enlarged in the 16th and 17th centuries, including a Renaissance courtyard with an open loggia, a Mannerist facade, and a castle chapel.

Up to today, the complex is privately owned and used as a hotel; after his abdication, Edward VIII, Duke of Windsor, and his wife Wallis Simpson spent their honeymoon here from 5 June to 7 September 1937.
