The Persepolis Fortification Archive and Persepolis Treasury Archive are two groups of clay administrative archives — sets of records physically stored together – found in Persepolis dating to the Achaemenid Persian Empire. The discovery was made during legal excavations conducted by the archaeologists from the Oriental Institute of the University of Chicago in the 1930s. Hence they are named for their in situ findspot: Persepolis. The archaeological excavations at Persepolis for the Oriental Institute were initially directed by Ernst Herzfeld from 1931 to 1934 and carried on from 1934 until 1939 by Erich Schmidt.

Persepolis was the ceremonial capital of the Achaemenid Empire. It is situated in the plains of Marvdasht, encircled by southern Zagros mountains, Fars province of Iran. It is one of the key Iranian Cultural heritages. The city of Shiraz is situated 60 km (37 mi) southwest of Persepolis. UNESCO declared the ruins of Persepolis a World Heritage Site in 1979.
