Count (later Prince) Andrey Kirillovich Razumovsky[a] (2 November 1752 – 23 September 1836) was a Russian diplomat who spent many years of his life in Vienna.

The elder Rasumovsky's late Baroque palace on the Nevsky Prospekt is a minor landmark in Saint Petersburg.

In 1808, he established a house string quartet consisting of Ignaz Schuppanzigh, Louis Sina, Franz Weiss, and Joseph Linke.

[3] Razumovsky built a magnificent Neoclassic palace worthy of the representative of Alexander I, at his own expense and to the designs of Louis Montoyer, on the Landstraße, quite close to Vienna, and filled it with antiquities and modern works of art.

[5] Razumovsky converted to Roman Catholicism from his native religion, Russian Orthodoxy, under the influence of his second wife, Countess Konstanze von Thürheim (1785–1867), member of uradel noble family from Swabia and sister of his friend Lulu von Thürheim, whom he married in February 1816.
