ʿAzīz Shaykh (Turki/Kypchak and Persian: عزیز شیخ; Oziz in the Russian chronicles) was Khan of the Golden Horde in 1364–1367.
The only specific testimony regarding his ancestry comes from the notoriously unreliable account of Muʿīn-ad-Dīn Naṭanzī (previously known as the "Anonymous of Iskandar"), according to whom ʿAzīz Shaykh was the son of the ephemeral khan Tīmūr Khwāja.
[6] Another interpretation makes ʿAzīz Shaykh the successor of Murād in Gülistan in 1363, taking over Sarai only later, in 1365, from Mamai's protégé ʿAbdallāh.
Apparently changing tactics, ʿAzīz Shaykh next granted a diploma of investiture (jarlig) with the Grand Principality of Vladimir to Dmitrij Konstantinovič of Suzdal', delivered by the khan's envoy Urusmandy and the prince's son, Vasilij Dmitrievič Kirdjapa.
When the autonomous emir of Bolghar, Pūlād Tīmūr, raided the lands of Nižnij Novgorod in 1367 and suffered defeat at the hands of the Russians, ʿAzīz Shaykh had him executed and replaced with his own appointee, Asan (Ḥasan).
