Jacob Kroger (d. 1594), was a German goldsmith who worked for Anne of Denmark in Scotland and stole her jewels. Kroger was a citizen of the Principality of Lüneburg, ruled by Anne of Denmark's brother-in-law, Henry Julius, Duke of Brunswick-Lüneburg. He completed his apprenticeship as a goldsmith at Lüneburg in 1575 instructed by the master goldsmiths Tönnies Dierssen or Dirksen and Steffen Ulrichs or Olrikes. Dierssen, whose hallmark was an antelope, made objects such as highly decorative spoons, and cups. Kroger's Lüneburg contemporaries Luleff Meier and Dirich Utermarke made a mirror frame decorated with theme of Nebuchadnezzar from the Book of Daniel.
