The word-historical interpretation of the place name of Beinum indicates that the village originated in the 5th/6th century. It coincides with the beginning of salt production in the Salzgau, i.e. in the region between Vepstedt, Kniestedt (both now Salzgitter-Bad) and Gitter.

The first documentary mention comes from a list of goods of the Goslar cathedral monastery. The directory was compiled by the cathedral scholastic Thietmar between 1174 and 1195.

The place name later changed from Behem (1174) to Benem (1209, in a document from Pope Innocent III), Beinem (1225), Beinum (1278), Beynum (1356) and Benum (1400). Since 1548, the current place name Beinum has been used consistently in the documents.
