Shahraplakan (Classical Armenian: , translit. Šahrapłakan), rendered Sarablangas (Σαραβλαγγᾶς) in Greek sources, was a Sassanid Persian general who participated in the Byzantine-Sassanid War of 602–628.
Shahraplakan first appears in 624, when the Persian shah Khosrau II (r. 590–628) entrusted him with the command of the so-called "New Army", composed of the regiments of Khosroēgetai and Perozitai according to Theophanes the Confessor. With this army, Shahraplakan was to counter the Byzantine emperor Heraclius (r. 610–641), who had invaded Persarmenia and was wintering in Caucasian Albania. Shahraplakan's army was successful in recovering many towns and driving the Byzantines back to the Siwnik area, and sought to capture key passes so as to prevent Heraclius from descending south into northwestern Persia (Adurbadagan). Heraclius, however, managed to avoid encirclement through a series of maneuvers. Shahraplakan followed him but did not engage him, hoping first to join with the army led by another Persian general, Shahrbaraz. Although Heraclius launched several sorties against Shahraplakan to prevent this, the two Persian armies eventually joined. Encouraged by reports from Byzantine deserters, the two Persian generals decided not to await the arrival of a third army under their rival Shahin, but to attack Heraclius. In the battle that followed, the Sassanid Persians were defeated.
