Yelizaveta Osipovna Belogradskaya (1739 — ca. 1764 [?]) was a Russian Imperial Court opera singer.
She was born in St. Petersburg, the daughter of Osip Bilohradsky, a court singer and the niece of Timofiy Bilohradsky, a court lutenist. She was a kammermädchen at the court[1] of the Empress Elizaveta Petrovna.
In 1753 she performed the part of Procris in Francesco Araja's opera "Cephalus and Procris", which was the first opera set in Russian,[2] with the text by Aleksandr Sumarokov. She sang in G.P. Raupach's "The Refuge of Virtue" and "Alcesta". Belogradskaya appeared at court concerts and festivities as a singer and harpsichord player.
She died in the 1760s and was interred at the Alexander Nevsky Lavra.
