Hans Krell (c. 1490 – 1565 or 1586), also Krehl ou Kreil, was a German painter of the Renaissance, mainly known as a portrait painter. He is thought to have been born in Crailsheim or Ansbach, and died in Leipzig.
Hans Krell started his career as court painter of George the Pious, Margrave of Brandenburg-Ansbach in Ansbach. He then entered into the service of King Louis II of Hungary in Prague and Buda, where he was employed as court portraitist in the years 1522–1526. He is later recorded in Leipzig (from 1531) and in Freiberg in Saxony (since 1534). Krell was known as the Fürstenmaler (Painter of Princes) in service of the German Princes – Albrecht of Brandenburg-Ansbach, Duke in Prussia, Hedwig Jagiellon, Electress of Brandenburg and the Elector Augustus of Saxony. His paintings of Saxon princes in the ceremonial hall and the council chamber of the Old Town Hall in Leipzig were continually being completed.
