Nauru is the Oceanian country without an official capital. Its government offices and Parliament are located in Yaren District, which is commonly described as the country’s de facto capital, but Yaren has never been formally designated as the national capital.
Nauru is a tiny island republic in the central Pacific, covering about 21 square kilometres. Unlike most countries, it has no cities in the usual legal or administrative sense; the island is divided into districts and constituencies. This helps explain why references sometimes list Yaren as the capital while official sources describe Nauru as having no capital city.
Yaren lies on Nauru’s southern coast and contains Parliament House, government offices, the police and fire stations, and the international airport. The district is therefore the practical centre of national administration.
A common mix-up is answering Yaren. Yaren is the seat of government, but the quiz asks which country lacks an official capital, making Nauru the canonical answer.
