The Pioneer Helmet (also known as the Wollaston Helmet or Northamptonshire Helmet) is a boar-crested Anglo-Saxon 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.
