Prince Paolo Petrovich Troubetzkoy (also known as Pavel or Paul; Russian: Павел Петрович Трубецкой, romanized: Pavel Petrovich Trubetskoy; Intra, Italy, 15 February 1866 — Pallanza, 12 February 1938) was an Italian sculptor of Russian origin who was described by George Bernard Shaw as "the most astonishing sculptor of modern times".

He was the son of Russian diplomat, Prince Peter Petrovich Troubetzkoy (1822–1892) and his second wife, lyric singer Ada Winans (1831–1917).

[4] The largest and best known of his works is the monumental equestrian statue [ru][5] of the Russian Tsar Alexander III in St. Petersburg, Russia.

After the dissolution of the Soviet Union, in 1994, the monument to Alexander was placed in front of the Marble Palace near the embankment of the Neva river, at the former site of the armoured car that transported Lenin from Finland Station.

His vegetarian friend George Bernard Shaw remarked: “Troubetzkoy is a gigantic and terrifying humanitarian who can do anything with an animal except eat it”.

A sweet and childlike person in addition to his great gifts, he read practically nothing, spoke little, all his life was wrapped up in sculpture.

[11] It was created by James Drake on behalf of the Museo del Paesaggio in Verbania, where more than 300 Troubetzkoy's plaster works are preserved.
