Ahmad ibn al-Hasan al-Kalbi was the second Kalbid Emir of Sicily. He was the son of the first Kalbid emir, al-Hasan ibn Ali al-Kalbi, who ruled the island on behalf of the Fatimid Caliphate. Ahmad succeeded his father in May 953 until 968, apart from a brief interruption in 958/9. In the 960s, he led the completion of the Muslim conquest of Sicily by capturing the last Byzantine strongholds of Taormina and Rometta and defeating a Byzantine relief expedition. He was recalled to Ifriqiya to participate in the upcoming Fatimid conquest of Egypt, and died there shortly after.
