Razumovsky or Rozumovsky (Russian: Разумовский, Ukrainian: Розумовський, formerly transliterated as Rasumowski, Rasumofsky and Rasoumofsky) is a Ukrainian-Russian comital family whose remaining branch went into exile in Austria in the early 19th century. Notable representatives include:

• Aleksey Grigorievich Razumovsky (1709-1771) - favorite and morganatic husband of Empress Elizabeth, created Count of the Holy Roman Empire in 1742 and Count in Russia in 1745.
• Kirill Grigorievich Razumovsky (1728-1803) - officially his younger brother, rumored to be a son from an earlier marriage, the last hetman of Left (1750-1764) and Right (1754-1764) Bank Ukraine, last Duke of the Zaporozhian Host (1754-1769), created Count of the Russian Empire in 1745.
• Aleksey Kirilovich Razumovsky (1748-1822) - the latter's first son, minister of education of the Russian Empire from 1806-1816, highly criticised by Pushkin for his reactionary stance;
• Andrey Kirilovich Razumovsky (1752-1836) - Kirill's second son, who was the Extraordinary and Plenipotentiary Ambassador of the Russian Empire at the Congress of Vienna. Andrey was created the HSH Prince in 1815 and settled there in the end, dying with no progeniture, whereby his title became extinct. Infamous for his participation in the murder of Gustav III of Sweden and Paul I of Russia, he was architect of the Second Partition of Poland. He is mostly remembered for his patronage of the arts, especially the composer Ludwig van Beethoven: Beethoven both wrote the Razumovsky Quartets (Op. 59 Nos. 1, 2, and 3) for Andrey and dedicated the 5th and 6th Symphony to him.
