Sasanian Armenia, also known as Persian Armenia and Persarmenia, may either refer to the periods in which Armenia was under the suzerainty of the Sasanian Empire or specifically to the parts of Armenia under its control such as after the partition of 387 when parts of western Armenia were incorporated into the Eastern Roman Empire while the rest of Armenia came under Sasanian suzerainty but maintained its existing kingdom until 428.

The Sasanian Empire or Sassanid Empire, officially known as Eranshahr, was the last Iranian empire before the early Muslim conquests of the 7th to 8th centuries. Named after the House of Sasan, it endured for over four centuries, from 224 to 651, making it the second longest-lived Persian imperial dynasty after the Arsacids of the Parthian Empire.
