What is Harry Potter's blood type?

Published in Harry Potter Lore 1 min read

Harry Potter does not have a defined blood type (A, B, O, AB) in the Harry Potter series. The "blood" referred to in the series relates to his wizarding heritage: Harry Potter is a half-blood wizard.

Understanding "Blood Status" in Harry Potter

In the world of Harry Potter, "blood status" refers to a witch or wizard's magical lineage. It's a controversial and often prejudiced concept, particularly within the pure-blood supremacist ideology of characters like Voldemort and his followers. The main categories are:

  • Pure-blood: Wizards and witches with an entirely magical ancestry, with no Muggles (non-magical people) in their family tree.
  • Half-blood: Wizards and witches with a mix of magical and Muggle ancestry. This is Harry's status, as his mother, Lily Potter, was Muggle-born, and his father, James Potter, was pure-blood.
  • Muggle-born: Witches and wizards born to non-magical parents.

Therefore, when characters discuss "blood," they are referring to this heritage and not a medical blood type.
