The Choiseul pigeon (Microgoura meeki) is an extinct species of bird in the pigeon and dove family, Columbidae. It was endemic to the island of Choiseul in the Solomon Islands, although there are unsubstantiated reports that it may once have lived on several nearby islands. The last confirmed sighting was in 1904. Other common names were Solomons crested pigeon, Solomon Islands crowned-pigeon and Kuvojo.^[1]

The Choiseul pigeon was monotypic within the genus Microgoura and had no known subspecies. Its closest living relative is believed to be the thick-billed ground pigeon, and some authors have suggested that the Choiseul pigeon may be a link between that species and the crowned pigeons. The adult pigeon was largely blue-grey, with a buffy orange belly and a distinctive slaty-blue crest. It is unknown how this crest was held by the bird in life. The bird's head sported a blue frontal shield surrounded by black feathers and a bicoloured beak. The wings were brown and the short tail was a blackish purple. It was described as having a beautiful rising and falling whistling call.

As the bird became extinct before significant field observations could be made, not much is known about its behaviour. It is believed to have been a terrestrial species that laid a single egg in an unlined depression in the ground. It roosted in pairs or small groups of three or four in small shrubs and was reportedly very tame, allowing hunters to pick it up off its roost. The Choiseul pigeon lived in lowland forests, particularly in coastal swampy areas that lacked mangroves. It was only recorded by Albert Stewart Meek, who collected six adults and an egg from the northern part of the island in 1904. Despite many subsequent searches, the bird has not been definitively reported since. It is believed to have been rare when Meek collected his specimens. The indigenous peoples reported that the species was driven to extinction due to the introduction of cats, as the pigeon had never previously confronted a carnivorous mammal on Choiseul. The last unconfirmed report of a Choiseul pigeon was in the early 1940s, and the species is considered extinct.
