Nothobranchius (Peters, W., 1868) is a genus of freshwater annual fish from East Africa. They have very small distributions, and consequently there are many species: as of April 2005 close to 50 nominal species, not counting varieties. They are a typical annual killifish, part of the order Cyprinodontiformes.

Etymology: Greek "nothos": false, spurious, and "branchia": gill.
