Syedna Mohammad Ezzuddin (Arabic: سيدنا محمد عزالدين‎) (died 1539 / 27th Safar, AH 946AH in Zabid -Yemen) was the 23rd Dai of the Dawoodi Bohra, a sub-sect of Isma'ili Shi'i Islam. The Dawoodi Bohra trace their belief system back to Yemen, where it evolved from the Fatimid Caliphate and where they were persecuted due to their differences from mainstream Sunni Islam and Zaydi Islam. Around 1567 CE, the Dawat (the sect's religious organisation) was relocated to Gujarat, India.
