Abu Talib Yahya (951 - 1033) was an imam of the Zaydiyyah sect in 1020–1033.

Like his elder brother and predecessor al-Mu'ayyad Ahmad, Abu Talib Yahya was a prominent man of learning and a descendant of Imam Hasan bin Ali. He succeeded al-Mu'ayyad Ahmad in the imamate of the Zaidi territories in Gilan and Deylaman in Persia, formally as "caliph".^[1] At this time there were two major Zaidi territories, namely the area south of the Caspian Sea and the highlands of Yemen. For many years after the death of imam al-Mahdi al-Husayn in 1013, no local imam was appointed in the Yemeni territory. In Zaidi historiography, al-Mu'ayyad Ahmad and Abu Talib Yahya are sometimes listed as such, although they never visited Yemen.^[2]
