J.K. Rowling’s charity focused on ending the institutionalisation of children is Lumos.
Rowling founded the organisation in 2005 as the Children’s High Level Group with the politician Emma Nicholson. It was renamed Lumos in 2010, taking its name from a light-producing charm in the Harry Potter books.
Lumos campaigns for children to grow up in families rather than in large residential institutions. Its work has included supporting family-based care, helping reform child-protection systems, and advocating for children separated from their families.
The charity’s name is sometimes confused with a Harry Potter fan organisation or a fictional institution. Lumos is a real international charity, and its mission concerns child welfare rather than publishing, film production, or wizarding-world merchandise.
