Qamar-ol-Moluk Vaziri (1905 – 5 August 1959), born Qamar Khanum Seyed Hosayn Khan, commonly known as "Qamar", was a celebrated Iranian singer, who was also the first woman of her time to sing in public in Iran without wearing a veil. She is known as "the Queen of Persian music".
She began her career in singing at age 19 in 1924 when she performed at the Grand Hotel in Tehran. When she performed she was among men and without the veil. During another performance at the Palace Theater in Tehran, again without the veil, she was accompanied by Morteza Neidavoud, who she had met when she was 16, just a few years earlier. He encouraged her to study music under his tutelage and she studied and performed in 1924.
Vaziri and Neydavoud worked a lot together during her 3 decade long career and in 1956 accompanied her for her farewell performance. Her existing birth certificate, issued in Tehran in 1925, legally records her first name as "Qamar-ol-Moluk" and her last name as changed from "Seyed Hosayn Khân" to "Vazirizâdeh", a name she chose for herself in honor of the musician and theoretician of music Ali-Naqi Vaziri.
Vaziri retired from singing in 1956, having worked for over 30 years with songwriters and poets in Iran and having been recorded on several gramophone discs.
Vaziri died in 1959 in Shemiran. She is buried at Zahir o-dowleh cemetery.
