Ruvim Isayevich Frayerman (Руви́м Иса́евич Фраерма́н, 22 September 1891, in Mogilyov, Russian Empire, – 28 March 1972, Moscow, USSR) was a Soviet writer, poet, essayist and journalist.

A major component of the Socialist romanticism, Frayerman is best remembered as a children's literature author, whose novel Wild Dog Dingo or the Tale of the First Love [ru] (1939) became a popular Soviet film in 1962.

Frayerman joined the Red partisan unit fighting the Japanese troops nearby Nikolayevsk, then as a commissar travelled through Siberia, helping to maintain the Bolshevik rule in the regions inhabited by Tungus, Nivkh and Nanai people.

Many of Frayerman's works of the time – notably, Vaska-Gilyak (1929), Afanasy Oleshek (1933) and The Misfortunes of An-Senen (1935) – dealt with the life of the native peoples of Siberia, whom the author formed strong bonds with.

Among Frayerman's later books were Children's Best-Loved Author (Lyubimy Pisatel Detei, 1954, on Arkady Gaidar) and A Test for Soul (Ispytanye Dushi, 1966), the collection of sketches and essays.
