The Blue-rumped Parrot, Psittinus cyanurus, is a parrot found in the very southern tip of Myanmar, peninsular Thailand, Malaysia, Borneo, Sumatra and nearby islands. It is a small parrot (18 cm) and is primarily green with bright red underwing coverts, a reddish shoulder patch, and yellowish margins on the wing coverts. It is sexually dimorphic. The female has a grey-brown head. The male has a black mantle, red upper mandible, and blue head and rump.

It is the only member of the genus Psittinus.

There are three subspecies:

• P. c. cyanurus: Burma, Thailand, Malaysia, Singapore, Borneo, Sumatra.
• T. l. pontius: Mentawi Islands S from Siberut. Larger than the nominate subspecies.
• T. l. aabbottii: Simeulue. Male head mostly green except around eye and ears, black mantle smaller. Even larger than pontius

It is found in lowland forests, generally below 700m, in forest, open woodland, orchards and plantations, mangroves, dense scrub, and coconut groves. It occurs in flocks up to 20 birds. They eat seeds, fruit and blossoms.
