Sheikh Abdussamad Esfahani, (Persian: شیخ عبدالصمد اصفهانی), also spelled Abdul Samad, 'Abd al-Samad, or Abd-ul-Samad, was a famous Ilkhanid era Sufi of the 13th century.
After Abdussamad's death in 1299 CE, his disciple, the Ilkhanid vizier Zayn al-Din Mastaria, built a shrine in Natanz in his honor.
