Muhammad ibn Ibrahim ibn Habib ibn Sulayman ibn Samra ibn Jundab al-Fazari () (died 796 or 806) was a Muslim philosopher, mathematician and astronomer. Some sources refer to him as an Arab, other sources state that he was a Persian. Al-Fazārī translated many scientific books into Arabic and Persian. He is credited to have built the first astrolabe in the Islamic world. Along with Yaʿqūb ibn Ṭāriq and his father Ibrāhīm al-Fazārī he helped translate the Indian astronomical text by Brahmagupta (fl. 7th century), the Brāhmasphuṭasiddhānta, into Arabic as ', or the . This translation was possibly the vehicle by means of which the Hindu numerals were transmitted from India to Islam.
