Andres Juden was a 14th or 15th century German fencing master. His name signifies that he was Jewish, but nothing else is known about this master's life. He is not mentioned by Paulus Kal as being a member of the Fellowship of Liechtenauer, although it's possible that he was actually Andre Liegniczer, a member of the fellowship and author of at least four other treatises. Otherwise, his exact relation to the high master is uncertain.
Along with Jobs von der Nyssen, Nicklass Preußen, and "The Priest" Hans Döbringer, Andres is one of the four masters credited with writing the addendum to Johannes Liechtenauer's Recital found in the Nuremberg Hausbuch and the Glasgow Fechtbuch.
