Sais (Ancient Greek: Σάϊς, Coptic: Ⲥⲁⲓ) was an ancient Egyptian city in the Western Nile Delta on the Canopic branch of the Nile, known by the ancient Egyptians as Sꜣw. It was the provincial capital of Sap-Meh, the fifth nome of Lower Egypt and became the seat of power during the Twenty-fourth Dynasty of Egypt (c. 732–720 BC) and the Saite Twenty-sixth Dynasty of Egypt (664–525 BC) during the Late Period. On its ruins today stands the town of Sa el-Hagar (Arabic: صا الحجر) or Sa El Hajar.
