Mehrdad Avesta (Mohammand Reza Rahmani, Persian: مهرداد اوستا; 8 August 1930 – 6 May 1991) was an Iranian poet. He was born in Borujerd (on 8 August 1930) into a literature and art-oriented family. When he was young, he changed his first name from Mohammad Reza to Mehrdad and his family name from Rahmani to Avesta in order to show his passion for ancient Persian culture. He married two times in 1954 and 1966 and he had one son and three daughters. Avesta died in his office at Vahdat Hall of Tehran while he was editing a poem work.
