Count Pyotr Alexandrovich Rumyantsev-Zadunaisky (15 January 1725 – 19 December 1796) is one of the foremost Russian generals of the 18th century.

He governs Little Russia in the name of Empress Catherine the Great from the abolition of the Cossack Hetmanate in 1764 until Catherine's death 32 years later.

Monuments to his victories include Kagul Obelisk in Tsarskoe Selo (1772), Rumyantsev Obelisk on Basil Island (1798–1801), and a galaxy of Derzhavin's odes.
