Alzey (German pronunciation:[ˈaltsaɪ]) is a Verband-free town – one belonging to no Verbandsgemeinde – in the Alzey-Worms district in Rhineland-Palatinate, Germany. It is the fourth-largest town in Rhenish Hesse, after Mainz, Worms, and Bingen.

Alzey is one of the Nibelungenstädte – towns associated with the Nibelungenlied – because it is represented in this work by the character Volker von Alzey. Hence, Alzey is also known as Volkerstadt.
