Abad Syi'ah atau Abad Syiah adalah istilah historiografi yang kadang-kadang digunakan untuk menggambarkan periode antara tahun 945 dan 1055, ketika rezim Muslim Syiah, terutama Fatimiyyah dan Buwayhiyah, memegang kendali atas wilayah-wilayah pusat dunia Islam.[1][2]
The fact that they were Shīʿite, as were the Idrīsids, Fāṭimids, and Ḥamdānids, led scholars to refer to the period from the mid-10th to mid-11th century as the Shīʿite century.
