The Spessart is a hill chain in northwestern Bavaria and southern Hesse, Germany. On three sides it is bounded by the Main River, which describes a long curve. Two large cities are located at the foot of the Spessart: Aschaffenburg and Würzburg.
Although the Spessart is a roughly circular hill country, the main ridge extends from the southwest to the northeast. It is continued by the Odenwald in the southwest and by the Rhön in the northeast.
Its highest peak is the Geiersberg (586 m). Apart from the edges, the region is sparsely populated. Two nature parks called Bavarian Spessart and Hessian Spessart occupy large portions of the hills.
