The Byzantine–Sassanid War of 572–591 is part of an intense sequence of wars between the East Roman and Sassanid Persian empires that occupy the majority of the sixth and early seventh centuries.

It is also the last of the many wars between them to follow a pattern in which fighting is largely confined to frontier provinces (in Mesopotamia, Greater Armenia, and Syria) and neither side achieves any lasting occupation of enemy territory beyond this border zone.

It precedes a much more wide-ranging and dramatic final conflict in the early seventh century.

The result is the restoration of Khosrau II to the Sasanian throne in 591; Khosrau II gives the Constantinople-based Empire most of Persian Armenia and the western half of Caucasian Iberia.
