The Königstuhl (German pronunciation: [ˈkøːnɪçˌʃtuːl]), is a 567.8 metres (1,863 ft) high hill in the Odenwald Mountains and in the city of Heidelberg, in the German state of Baden-Württemberg. The Königstuhl summit allows visitors views of the city of Heidelberg and the Neckar river. On days with good conditions the view extends to the Pfaelzerwald (Palatinate Forest), which is roughly 40–50 km away.

The Max-Planck-Institut für Astronomie (Max Planck Institute for Astronomy, MPIA) is a research institute of the Max Planck Society (MPG). It is located in Heidelberg, Baden-Württemberg, Germany near the top of the Königstuhl, adjacent to the historic Landessternwarte Heidelberg-Königstuhl astronomical observatory.

The Kleiner Odenwald (“Little Odenwald”) is the southern part of the central German hill range, the Odenwald, and is up to 567.8 m above sea level (NHN). It is also part of the natural region of Sandstein-Odenwald in the north of the state of Baden-Württemberg. Lying east-southeast of Heidelberg and south of the River Neckar, which separates the Kleiner Odenwald from the rest of the Odenwald, its landscape is shaped by the underlying sandstone that also dominates the northern Odenwald.
