Trechtingshausen is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Mainz-Bingen district in Rhineland-Palatinate, Germany.

The Rhine Gorge is a popular name for the Upper Middle Rhine Valley, a 65 km section of the Rhine between Koblenz and Rüdesheim in the states of Rhineland-Palatinate and Hesse in Germany. It was added to the UNESCO list of World Heritage Sites in June 2002 because of its beauty as a cultural landscape, its importance as a route of transport across Europe, and the unique adaptations of the buildings and terraces to the steep slopes of the gorge.
