The Macgregor's Bird of Paradise, Macgregoria pulchra, also known as Macgregor's Giant Honeyeater, is a large (up to 40cm long) black crow-like bird with a large orange-yellow eye-wattles and black-tipped ochre primary wing feathers. The sexes are similar, with the male is slightly larger than female. It is the only member of the genus Macgregoria.

A monogamous species, it inhabits subalpine forests of New Guinea. The diet consists mainly of fruits. This puzzling and little-known species has traditionally been considered a Bird of Paradise, but is actually a honeyeater. Recent genetic evidence on the Macgregor's Giant Honeyeater confirms that it belongs to the Meliphagidae family . It is similar and closely related to the Smoky Honeyeater.

The name commemorates its discoverer, the administrator of British New Guinea Sir William MacGregor.

Due to small and declining population, the Macgregor's Giant Honeyeater is evaluated as Vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES.
