Aḥmad ibn Abī Ya‘qūb ibn Ja'far ibn Wahb ibn Waḍīḥ al-Ya‘qūbī (died 897/8), known as Ahmad al-Ya'qubi, or Ya'qubi (Arabic: اليعقوبي), was a Muslim geographer and perhaps the first historian of world culture in the Abbasid Caliphate.
He was a great-grandson of Wadih, the freedman of the caliph Al-Mansur. Until 873 he lived in Armenia and Khorasan, working under the patronage of the Tahirids Governors; then he traveled to India, Egypt and the Maghreb, and died in Egypt. He died in AH 284 (897/8).
His sympathies with Ahl al-Bayt are found throughout his works.
