鸮鹦鹉（毛利语：kākāpō，夜鹦鹉的意思），学名：Strigops habroptila（命名来自希腊语，strigos，strix一词的属格：鸮；ops：面孔；habros：柔软的，ptilon：羽毛；全名解作拥有如鸮形目面孔、及羽毛柔软的雀鸟），是一种夜行性鹦鹉，全身披着黄绿色的细点，是新西兰的特有种。

牠面上有鸮形目独有的面盘羽毛排列，有独特的感受器：羽须，大而灰的喙，短腿大脚，翅膀及相对地短的尾巴。牠的不同习性使牠成为一种相当独特的品种——牠是世上唯一一种不会飞行的鹦鹉，体型冠绝同类、夜行性、草食性，表现出两性异形的身体结构，基础代谢率缓慢，雄性不负责照顾幼小，也是唯一一种实行一夫多妻制、并实行求偶场交配制度的鹦鹉。有研究指牠也可能是世界上寿命最长的鸟类，普遍相信可达60年或以上。

The kakapo (Māori: kākāpō or night parrot), Strigops habroptilus (Gray, 1845), also called owl parrot, is a species of large, flightless, nocturnal, ground-dwelling parrot of the super-family Strigopoidea endemic to New Zealand.

It has finely blotched yellow-green plumage, a distinct facial disc of sensory, vibrissa-like feathers, a large grey beak, short legs, large feet, and wings and a tail of relatively short length. A combination of traits make it unique among its kind; it is the world's only flightless parrot, the heaviest parrot, nocturnal, herbivorous, visibly sexually dimorphic in body size, has a low basal metabolic rate and no male parental care, and is the only parrot to have a polygynous lek breeding system. It is also possibly one of the world's longest-living birds. Its anatomy typifies the tendency of bird evolution on oceanic islands, with few predators and abundant food: a generally robust physique, with accretion of thermodynamic efficiency at the expense of flight abilities, reduced wing muscles, and a diminished keel on the sternum. Like many other New Zealand bird species, the kakapo was historically important to the Māori, the indigenous people of New Zealand, appearing in many of their traditional legends and folklore. It was hunted and used as a resource by Māori, both for its meat as a food source and for its feathers, which were used to make highly valued pieces of clothing. It was also sometimes kept as a pet.
