Zamoyski Code (Polish: Kodeks Zamoyskiego or Zbiór praw sądowych na mocy konstytucji roku 1776 przez J.W. Andrzeja Zamoyskiego ekskanclerza koronnego ułożony... [Collection of court laws requested by constitution of 1776 designed by former chancellor Andrzej Zamoyski]) was a major, progressive legislation, proposed by Andrzej Zamoyski, Grand Chancellor of the Crown of the Polish–Lithuanian Commonwealth, in 1776. This legislation was an attempt of codification of the previously uncodified law of the Commonwealth. It was opposed by several conservative and foreign factions and eventually rejected by the sejm of 1780.
