The city is named after Wulfrun, who founded the town in 985, from the Anglo-Saxon Wulfrūnehēantūn ("Wulfrūn's high or principal enclosure or farm"). Prior to the Norman Conquest, the area's name appears only as variants of Heantune or Hamtun, the prefix Wulfrun or similar appearing in 1070 and thereafter. Alternatively, the city may have earned its original name from Wulfereēantūn ("Wulfhere's high or principal enclosure or farm") after the Mercian King, who tradition tells us established an abbey in 659, though no evidence of an abbey has been found. The variation Wolveren Hampton is seen in medieval records, e.g. in 1381.
