Zaglossus attenboroughi, also known as Attenborough's long-beaked echidna or locally as Payangko, is one of three species from the genus Zaglossus that inhabits the island of New Guinea. It lives in the Cyclops Mountains, which are near the cities of Sentani and Jayapura in the Indonesian province of Papua in Western New Guinea. It is named in honour of naturalist Sir David Attenborough.

It is currently classified as critically endangered by the IUCN, and there had been no confirmed sightings between its initial collection in 1961 and November 2023, when the first video footage of a living individual was recorded.
