Abu Mansur Muhammad Ibn Ahmad Daqiqi Tusi (935/942-976/980: Persian: ابو منصور محمد بن احمد دقیقی), sometimes referred to as Daqiqi (also Dakiki, Daghighi, Persian: دقیقی), was an early Persian poet who is said to have been born in Tus in Iran; or in Balkh, located in modern-day Afghanistan; as well as in Samarqand or Bukhara, both in today's Uzbekistan and Marv in today's Turkmenistan.
Daqiqi wrote an epic history of Iran which is begun by history of Zarathushtra and Gashtasb. Questions have been raised as to whether Daqiqi harboured some Zoroastrian beliefs, or was simply promoting Sassanian cultural trends in the wake of Samanid domination. Nevertheless, he is viewed to have been a Zoroastrian convert to Islam. A large number of couplets by him were included in the epic Shahname (Book of Kings) by the Persian epic poet Ferdowsi. Daqiqi was murdered by his favorite slave.

Various biographers have named Bukhara, Samarqand, Balḵ, Marv, and Ṭūs as his birthplace; according to Moḥammad ʿAwfī (..), it was at Ṭūs, and for several reasons his report seems more probable.
