Nicolas Claudianus, died 1522) was a Bohemian physician and scholar, sometime publisher, and member of the Czech or Bohemian Brethren, a Protestant group formed in 1457 rooted in the teachings of Jan Hus. He printed the oldest map of Bohemia in 1518, hailed by Nordenskjold as 'the first map on which the different religious and political conditions of a country are denoted.'
