Tiki culture is an American-originated art, music, and entertainment movement inspired by Polynesian, Melanesian, and Micronesian cultures, and by Oceanian art. Influential cultures to Tiki culture include Australasia, Melanesia, Micronesia, Polynesia, the Caribbean Islands, and Hawaii. The name comes from Tiki, the Māori name for the first human, often represented in the form of hei-tiki, a pendant and important taonga. The hei-tiki was often appropriated by Europeans as a commercialised good luck charm, hence the name of Tiki culture. Despite spanning over 10,000 miles and including many different unrelated cultures, religions, and languages, Tiki aesthetic is considered by some to be amalgamated into one "fantasia of trans-Pacific cultures" and "colonial nostalgia". Because of this, and the simplistic view of the Pacific taken by the aesthetic, Tiki culture has often proved controversial.
