Nauru, officially known as the Republic of Nauru, is a small island country located in the Pacific Ocean. It is the third smallest country in the world by area, covering just 21 square kilometers. Nauru is a phosphate rock island with a population of around 10,000 inhabitants.

The country gained independence in 1968 and is a parliamentary republic with a president as its head of state. Nauru's economy is heavily dependent on phosphate mining, although efforts have been made to diversify into other industries such as offshore banking and fishing.

Nauru is known for its unique bird species and coral reefs, making it a popular destination for ecotourism. The country faces challenges such as environmental degradation due to mining activities and issues related to obesity and health due to a high dependence on imported food. Nauru is a member of the United Nations and the Pacific Islands Forum.
