Deltaretrovirus is a genus of the Retroviridae family. It consists of exogenous horizontally transmitted viruses found in several groups of mammals. As of 2023^[update], ICTV lists under this genus the Bovine leukemia virus and three species of primate T-lymphotropic virus.

The genus of viruses is known for its propensity to target immune cells and oncogenicity, evident in the names of the four named species.^[1] Infection is usually asymptomatic, but inflammation and cancer can develop over time.^[2]
