Ostad Sa'id Hormozi (1898–1976) was an Iranian musician who is remembered for his efforts to "promote authentic Iranian music" and pass it to modern musicians. He was born in one of the old neighborhoods of Tehran called Sangalaj. He was a prominent radif master and virtuoso tar and setar player.

A setar is a stringed instrument, a type of lute used in Persian traditional music, played solo or accompanying voice. It is a member of the tanbur family of long-necked lutes with a range of more than two and a half octaves. Originally a three stringed instrument, a fourth string was added by Mushtaq Ali Shah by the mid 19th century. It is played with the index finger of the right hand.
