Illiam Dhône or Illiam Dhôan (literally meaning 'Brown William' in English) (14 April 1608 – 2 January 1663), also known as William Christian, was a Manx politician and depending on viewpoint, patriot, rebel or traitor.
He was a son of Ewan Christian, a deemster.
In Manx, Illiam Dhône literally translates to Brown William — a name he received due to his dark hair, and in English he was called Brown-haired William.
