Yahya ibn Tamim (Arabic: يحي بن تميم) was the Zirid ruler of Ifriqiya from 1108 to 1116 CE.^[1]

Yahya inherited the throne from his father, Tamim ibn al-Mu'izz, in 1108.^[1] Tamim's long reign had left the Zirids weakened, as the Hilalian invasions had reduced their authority to the Tunisian coast, from Sousse to Gabes. Furthermore, Ifriqiya now faced a powerful Christian enemy in the form of the Italo-Norman Kingdom of Sicily to the north.^[1]

In response, Yahya built a strong fleet, with which he raided the Republic of Genoa and Sardinia.^[1] He was succeeded by his son, Ali ibn Yahya.^[1]
