The red-crowned parakeet or red-fronted parakeet (Cyanoramphus novaezelandiae), also widely known by its Māori name of kākāriki, is a small parrot from New Zealand. It is characterised by its bright green plumage and the red pattern on its head.

The Lord Howe parakeet (Cyanoramphus subflavescens), also known as the Lord Howe red-fronted parakeet, is an extinct parrot endemic to Lord Howe Island in the Tasman Sea, part of New South Wales, Australia. It was described as full species by Tommaso Salvadori in 1891, but subsequently it has been regarded as subspecies of the red-crowned parakeet. In 2012, the IOC World Bird List recognised it as species.
