Bombus melanopygus, the black-tailed bumble bee,black tail bumble bee or orange-rumped bumblebee, is a species of bumblebee. It is native to western North America from British Columbia to California, and as far east as Idaho.

This bumblebee can utilize a number of habitat types, including agricultural and urban areas. It is "one of the few bumblebees still found regularly in San Francisco". It feeds on many types of plants, including manzanitas, wild lilacs, goldenbushes, wild buckwheats, lupines, penstemons, rhododendrons, willows, sages, and clovers. It nests underground or aboveground in structures.

This species is a host to the zombie fly (Apocephalus borealis).

The second and third abdominal segments are red in northern populations and black in southern; individuals with black segments were previously known as Bombus edwardsii, a separate species. Genetic analyses support the conclusion that the two forms are the same species, with B. edwardsii as a synonym.
