The Pioneer Helmet is an Anglo-Saxon boar-crested helmet from the late seventh century found in Wollaston, Northamptonshire, United Kingdom. It was discovered during a March 1997 excavation before the land was to be mined for gravel and was part of the grave of a young man. Other objects in the grave, such as a hanging bowl and a pattern welded sword, suggest that it was the burial mound of a high-status warrior.

Germanic boar helmets or boar crested helmets are attested in archaeological finds from England, Denmark and Sweden, dating to Vendel and Anglo-Saxon periods, and Old English and Old Norse written sources. They consist of helmets decorated with either a boar crest or other boar imagery that was believed to offer protection in battle to the wearer. They have also been proposed to be a costume for the ritual transformation into a boar, similar to berserkers, and to be associated with Freyr.
