The Alte Nahebrücke (English: Old Nahe Bridge) is a medieval stone arch bridge in Bad Kreuznach, in western Germany, dating from around 1300, that originally spanned the Nahe river and a neighbouring canal called the Mühlenteich (English: mill pond).

[1] The stone Alte Nahebrücke was built around 1300 by Simon II, Count of Sponheim-Kreuznach, who ruled the town, to replace a wooden bridge which connected settlements on either side of the Nahe river.

[2] The first recorded mention of the stone bridge was in 1332, when the Pauluskirche (English: St Paul's Church), which stands on Wörthinsel, the island between the canal and the river, was consecrated.

On Friday, 16 March 1945 the arm of the bridge spanning the river was blown up by German troops to hinder the approach of American forces.

There is also a house on the downstream side of the fourth pier, but its foundations are on an island which lies between the canal and the river, so it is not actually a bridge-supported building.
