Cornelius Johnson or Cornelis Janssens van Ceulen (bapt. 14 October 1593 – bur. 5 August 1661) was an English painter of portraits of Dutch or Flemish parentage. He was active in England, from at least 1618 to 1643, when he moved to Middelburg in the Netherlands to escape the English Civil War. Between 1646 and 1652 he lived in Amsterdam, before settling in Utrecht, where he died.
