Samian Decree is an Attic relief. The largest and most important fragment was discovered in 1888 during the excavations of the Acropolis of Athens, while two other fragments had already been found in 1876 in the Theatre of Dionysus. A fourth fragment was discovered later, probably among finds from the Acropolis excavations, and was added in 1903. It is kept in the Acropolis Museum in Athens.
