Nothobranchius attenboroughi is a species of brightly colored seasonal killifish in the family Nothobranchiidae.

It is currently known from ephemeral pools and marshes associated with the Grumeti River and other small systems draining into Lake Victoria at the east side of the lake, which ecological integrity is maintained by the congruence of its catchments largely within the Serengeti-Mara ecosystem.

[2] This species was named "in honour of Sir David Attenborough, in recognition of his dedicated efforts to promote biophilia: raising awareness of the wonders and beauties of nature for so many people worldwide, promoting awareness of the importance of biodiversity conservation, and above all, inspiring so many researchers in the field of natural history, including the authors.

"[2] The small and colourful Nothobranchius fishes inhabit ephemeral habitats in freshwater wetlands of Africa and have extreme life-history adaptations.

[3] Nothobranchius fishes are subject to high levels of threat, with 72% of the species falling into one of the Threatened Red List categories, as a consequence of habitat destruction of seasonal wetlands.
