A gammaretrovirus is a genus of the retroviridae family. Many species contain oncogenes and cause sarcomas and leukemias.

Examples are the murine leukemia virus, the feline leukemia virus, the feline sarcoma virus, and the avian reticuloendotheliosis viruses.

Many endogenous retroviruses, closely related to exogenous gammaretroviruses are present in the DNA of mammals (including humans), birds, reptiles and amphibians.
