J. K. Rowling’s charity founded to support vulnerable children is Lumos.
Rowling established the organization in 2005 under the name Children’s High Level Group, with the goal of improving the lives of disadvantaged children. It was later renamed Lumos, a reference to the light-producing spell in the Harry Potter series. The charity campaigns for children to grow up in families and communities rather than in institutions.
Lumos has worked internationally on deinstitutionalization, family support, and alternatives to residential care. Its focus is broader than supplying books or funding schools: it addresses systems that separate children from families and seeks community-based care and protection.
The name can be confused with other charitable organizations because Rowling has supported several causes. Lumos is specifically associated with children’s rights and ending the institutionalization of children. Its name is also a fictional magical term, but the organization itself is a real charity with a social-care mission.
