The House of Repnin (Russian: Репнин), is an ancient Russian princely family, claiming descent from the Olgovichi branch of Rurik dynasty.
They held the hereditary title of Knyaz in the Empire of Russia.

The family traces its name to Prince Ivan Mikhailovich Obolensky (+1523), nicknamed Repnya, i.e., "bad porridge".
Like other Princes Obolensky, he descended from Mikhail Vsevolodovich, prince of Chernigov, who, in 1246, was assassinated by the Mongols.
