Tittmoning (German: [ˈtɪtmɔnɪŋ] ) is a town in the district of Traunstein, in Bavaria, Germany.

It is situated in the historic Rupertiwinkel region, on the left bank of the river Salzach, which forms the border with the municipality of Ostermiething in the Austrian state of Salzburg. The two communes are linked by a bridge. Tittmoning is located about 30 kilometres (19 mi) northwest of the Salzburg city centre.

The settlement of Titamanninga was first mentioned about 790 AD, then a possession of St Peter's Abbey, Salzburg. After the Archbishops of Salzburg had achieved immediate status in the late 13th century, Tittmoning Castle was built as a border fortress against the incursions by the Dukes of Bavaria. The episcopal administrator of the castle and its environs was called burgrave (Burggraf), as was Ulrich von Wispeck in 1282. Tittmoning was occupied by the forces of the German king Louis the Bavarian during his conflict with the papacy in 1324; nevertheless, he restored it to the Salzburg archbishops three years later.

Temporarily given in pawn to Bavaria, the unlucky Prince-Archbishop Wolf Dietrich Raitenau had to cede the castle to the Bavarian duke Maximilian I in 1611; it was repurchased by his successor Archbishop Mark Sittich von Hohenems and rebuilt as a hunting lodge according to plans designed by Santino Solari. By the 17th century, the castle had finally lost its character of a fortress and became the summer residence of the Prince-Archbishops of Salzburg. Upon the Congress of Vienna, the Rupertiwinkel region finally fell to the Kingdom of Bavaria and Tittimoning Castle, damaged by French troops during the Napoleonic Wars, passed under state-ownership.

In the early years of World War II, the castle was used as a prisoner-of-war camp for officers, Oflag VII-D. British and American citizens were also interned there (see Ilag VII Laufen and Tittmoning). They put on plays and sketches, including a performance of Hamlet by Shakespeare. Photos of these productions and paintings of the castle may be found here.

Joseph Ratzinger lived here as a child between 11 July 1929 and 5 December 1932. Later, he became a cardinal and in 2005, was elected Pope Benedict XVI.

A festival takes place here every year at the end of May, with theatrical presentations, medieval tournaments and jousting.
