The Niederwald monument (German: Niederwalddenkmal) is a monument located in the Niederwald, near Rüdesheim am Rhein in Hesse, Germany, built between 1871 and 1883 to commemorate the Unification of Germany. The monument is located within the Rhine Gorge, a larger UNESCO World Heritage Site. It overlooks the Rhine Valley and the town of Bingen on the far side.

The monument was constructed to commemorate the founding of the German Empire in 1871 after the end of the Franco-Prussian War. The first stone was laid on 16 September 1877 by Kaiser Wilhelm I. The sculptor was Johannes Schilling, and the architect was Karl Weißbach. The total cost of the work is estimated at one million gold marks. The monument was inaugurated on 28 September 1883. The 38 metres (125 ft) tall monument represents the union of all Germans.

The central figure is the 10.5 metres (34 ft) tall Germania figure. Her right hand holds the recovered crown, and her left holds the Imperial Sword.

Beneath Germania is a large relief depicting Kaiser Wilhelm I riding a horse with the nobility, army commanders, and soldiers. The relief has the lyrics to "Die Wacht am Rhein" (Watch on the Rhine) engraved.

The right side of the monument is considered the "peace statue", while the left is considered the "war statue."

The monument's main inscription is engraved on the pedestal of the Germania statue:

ZUM ANDENKEN AN DIE EINMUETHIGE SIEGREICHE ERHEBUNG DES DEUTSCHEN VOLKES UND AN DIE WIEDERAUFRICHTUNG DES DEUTSCHEN REICHES 1870–1871

In memory of the unanimous victorious uprising of the German people and of the reinstitution of the German Empire 1870–1871

The Niederwald [de] is a broad hill on the right bank of the Rhine located next to the tributary Wisper, opposite Bingen am Rhein. The hill forms the southwestern apex of the Taunus range. Its summit is covered by a dense forest of oak and beech. Its southern and western sides, which descend sharply to Rüdesheim am Rhein and Assmannshausen, are covered with vineyards. The monument is located at the edge of the forest, on the crest of the hill above Rüdesheim.

The Niederwalddenkmal can be reached by gondola lift (formerly a rack railway), from Rüdesheim to Niederwald, by car, by chairlift from Assmannshausen, or by trails on foot.
