Arcadia or Arcadia Aegypti was an ancient Roman province in northern Egypt. It was created between 386 and ca. 395 out of the province of Augustamnica and named for the reigning emperor, Arcadius. The province comprised most of the historical region known as "Heptanomis" ("Seven Nomes"), except for Hermopolis, which belonged to the Thebaid. In the Notitia Dignitatum, Arcadia forms one of six provinces of the Diocese of Egypt, under a praeses.
