Yaren (in earlier times Makwa/Moqua) is a district of the Pacific island country of Nauru. It is the de facto capital of Nauru and is coextensive with Yaren Constituency. It is also the fourth-least-populated capital in the world.

The district was created in 1968. Its original name, Makwa (or Moqua), refers to Moqua Well, an underground lake and primary source of drinking water for Nauruan people.

Yaren is located in the south of the island. Its area is 1.5 km (0.58 sq mi), and its elevation was 25 metres (82 feet) as of 2007. To the north of Yaren is Buada, to the east is Meneng and to the west is Boe.

Yaren has a marine tropical rainforest climate (Köppen Af) with hot, humid conditions across the year.

Yaren (and sometimes Aiwo) is usually listed as the capital of Nauru. However, this is incorrect; the republic does not have cities nor an official capital. Yaren is accepted by the United Nations as the "main district".

English and Nauruan, the official languages of Nauru, are spoken in the district.

• the Parliament House
