Mumu (Russian: «Муму») is a short story by Ivan Turgenev, a Russian novelist and story writer, written in 1854.

The story of Gerasim, a deaf and mute serf whose life of poverty is brought into sharp relief by his connection with Mumu, a dog he rescued, brought greater national attention to the cruelties of serfdom, and received praise for its brutal portrayal of this institution in Russian society.
