The longest place name on the planet is 85 letters long.

 People who live in Mamungkukumpurangkuntjunya Hill, Australia, need a little patience when it comes to learning to spell their hometown's name. But you know what? So do the folks from Lake Chargoggagoggman-chauggagoggchaubunagungamaugg in Massachusetts and Tweebuffelsmeteen-skootmorsdoodgeskietfontein, South Africa.

None of them have quite as much work to do when jotting down their address as those who live in Taumatawhakatangihanga-koauauotamateaturipukakapikimaung-ahoronukupokaiwhenuakitanatahu, New Zealand, though. At 85 letters long, this is the longest place name in the world.
