Seyyed Mohammad Hossein Behjat-Tabrizi (Persian: سید محمدحسین بهجت تبریزی) (1906-September 18, 1988), chiefly known by his pen name as Shahriar (شهریار), was an Iranian poet, writing in Persian and Azerbaijani.
Born in Tabriz, Shahriar came to Tehran in 1921 and continued his studies in the Dar ol-Fonoun high school and started studying medicine after graduation from Dar ol-Fonoun in 1924. But he fell in love, left his studies about a year before receiving his M.D. degree, and went to Khorasan. He returned to Tehran in 1935 and started working in the Agricultural Bank of Iran .
Shahriar published his first book of poems in 1929, with prefaces by Mohammad Taghi Bahar, Saeed Nafisi , and Pezhman Bakhtiari . His poems are mainly influenced by Hafez. His most famous poem Heydar-Baabaayaa Salaam, in Azerbaijani, is considered to be among the best modern poems in the language and has been turned into a few plays.
Shahriar was a supporter of the Islamic Republic government of Iran until his death, and his day of death is named the "national day of poem" in Iran.
It is claimed that he was addicted to opium, but that has never been confirmed officially.
