Wiglaf is a young well-regarded Swedish warrior of the Waegmunding clan, in Beowulf. His father was Weohstan, one of the champions of the Swedish kings who had slain the fugitive Swedish prince Eanmund and taken his sword.

Wiglaf is called the "last of the Waegmundings" and when his father was dead he took his father's sword (originally Eanmund's) and travelled to Geatland to join his kinsman Beowulf, the king of the Geats. When Beowulf entered the dragon's lair, only Wiglaf dared join him.
