Arcadia or Arcadia Aegypti was a Late Roman province in northern Egypt.
It was created between 386 and ca. 395 out of the province of Augustamnica and named for the reigning Byzantine emperor, Arcadius (395 to 408).
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 governor with the low rank of praeses.
