Hamdallah Mustawfi Qazvini (Persian: حمدالله مستوفى قزوینی, romanized: Ḥamdallāh Mustawfī Qazvīnī; 1281 – after 1339/40) was a Persian official, historian, geographer and poet. He lived during the last era of the Mongol Ilkhanate, and the interregnum that followed.
A native of Qazvin, Mustawfi belonged to family of mustawfis (financial accountants), thus his name. He was a close associate of the prominent vizier and historian Rashid al-Din Hamadani, who inspired him to write historical and geographical works. Mustawfi is the author of three works; Tarikh-i guzida ("Excerpt History"), Zafarnamah ("Book of Victory") and Nuzhat al-Qulub ("Hearts' Bliss"). A highly influential figure, Mustawfi's way of conceptualizing the history and geography of Iran has been emulated by other historians since the 13th century.
