Oligobombus is an extinct genus of bumblebee relatives in the tribe Bombini, containing the single species Oligobombus cuspidatus.

The genus and species were described by Antropov (2014) based on a single fore-wing from the Late Eocene Bembridge Marls Insect Bed on the Isle of Wight, England.

The fossil was described by re-examining a specimen in the Smith Collection.

The collection was originally made by A'Court Smith, and purchased by the Natural History Museum in 1877 and 1883.
