Taumata­whakatangihanga­koauau­o­tamatea­turi­pukaka­piki­maunga­horo­nuku­pokai­whenua­ki­tana­tahu is a hill near Pōrangahau, south of Waipukurau, in southern Hawke's Bay, New Zealand. The summit of the hill is 305 metres above sea level. The hill is notable primarily for its unusually long name, which is of Māori origin; it is often shortened to Taumata for brevity. It has gained a measure of fame as it is the longest place name found in any English-speaking country, and possibly the longest place name in the world, according to World Atlas. The name of the hill has been listed in the Guinness World Records as the longest place name. Other versions of the name, including longer ones, are also sometimes used.
