The haka (/ˈhɑːkə/;^[1] plural haka, in both Māori and English) is a ceremonial dance or challenge in Māori culture.^[2] It is a posture dance performed by a group, with vigorous movements and stamping of the feet with rhythmically shouted accompaniment. Although commonly associated with the traditional battle preparations of male warriors, haka have been performed by both men and women,^[3] and several varieties of the dance fulfil social functions within Māori culture.^[4][5] Haka are performed to welcome distinguished guests, or to acknowledge great achievements, occasions or funerals.

Kapa haka (performing arts, lit. line dance) groups are very common in schools.^[6] The main Māori performing arts competition, Te Matatini, takes place every two years.^[7]

New Zealand sports teams' practice of performing a haka before their international matches has made the haka more widely known around the world. This tradition began with the 1888–89 New Zealand Native football team tour and has been carried on by the New Zealand rugby union team ("All Blacks") since 1905.^[8] However, this is considered by some Māori to be a form of cultural appropriation.^[9][10]
