Amarna letter EA 100, titled: "The City of Irqata to the King" is a short-, to moderate-length clay tablet Amarna letter from the city-state of Irqata,, written to the Pharaoh of Egypt. Only one other city sent a clay tablet Amarna letter to the Pharaoh, namely Tunip, letter EA 59, titled: "From the Citizens of Tunip".

The Amarna letters are an archive, written on clay tablets, primarily consisting of diplomatic correspondence between the Egyptian administration and its representatives in Canaan and Amurru, or neighboring kingdom leaders, during the New Kingdom, spanning a period of no more than thirty years between c. 1360–1332 BC. The letters were found in Upper Egypt at el-Amarna, the modern name for the ancient Egyptian capital of Akhetaten, founded by pharaoh Akhenaten (1350s–1330s BC) during the Eighteenth Dynasty of Egypt.
