Nāṣir al-Dīn Sökmen II (died 1185) was the Shāh-i Arman, the ruler of the Turkoman principality centred on Ahlat, from 1128 until his death.
He married Shāhbānū, daughter of ′Izz al-Dīn Saltuq II, ruler of the Saltukids of Erzurum.
He and his wife both engaged in major building projects that brought the Shāh-i Armanid state to its zenith.
She employed an engineer named Qaraqush, who completed the massive construction project in only a few months.
None of these works have been survived, all being destroyed after the siege of Ahlat in 1229–30, when the Khwarazmshah Jalāl al-Dīn captured the city.
