Pyotr Konstantinovich Leshchenko (Russian: Пётр Константинович Лещенко; 2 June 1898 – 16 July 1954), a singer in the Russian Empire, Romania and later the Soviet Union, is universally considered "the King of Russian Tango" and specifically known for his rendition of "Serdtse"—a tango, sung unusually not in Spanish but in Russian.
