The Ptolemaic Decrees were a series of decrees by synods of ancient Egyptian priests. They were issued in the Ptolemaic Kingdom, which controlled Egypt from 305 BC to 30 BC. In each decree, the benefactions of the reigning pharaoh, especially towards the priesthood, are recognised, and religious honours are decreed for him.^[1]

Two decrees were issued under Ptolemy III Euergetes (the Decree of Alexandria and Decree of Canopus), another under Ptolemy IV Philopator (the Raphia Decree), and others under Ptolemy V Epiphanes (the Decree of Memphis and the two Philensis Decrees). Multiple copies of the decrees, inscribed on stone steles, were erected in temple courtyards, as specified in the text of the decrees.^[2]

There exist three copies plus a fragment of the Decree of Canopus, two copies of the Memphis Decree (one imperfect), and two and a half copies of the text of the Rosetta Stone, including the copy on the Nubayrah Stele and a temple wall inscription with edits, or scene replacements, completed by subsequent scribes.

The Decree of Alexandria was issued on the 13rd of Gorpiaios = 3 december 243 BCE. It proclaimed that statues of Ptolemy III and his wife Berenice II as well as a shrine for them should be set up in each temple to worship them as beneficent gods.^[3]

The Decree was issued on 7 Appellaios (Mac.) = 17 Tybi (Eg.) year 9 of Ptolemy III = Thursday 7 March 238 BCE (proleptic Julian calendar).
