Which country's flag features a twelve-pointed star?

Nauru's flag features a twelve-pointed white star.

The star sits just below a narrow yellow horizontal stripe on a dark blue field. Its position is symbolic: the stripe represents the Equator, while the star marks Nauru's location one degree south of it. The blue field represents the Pacific Ocean, and the star's white colour recalls phosphate, a resource that shaped Nauru's modern history.

The star's twelve points represent Nauru's twelve original tribes. They are a cultural reference, not a count of islands or administrative regions. Nauru is a single raised coral island, and its phosphate deposits were formed from accumulated seabird guano over a very long period.

The flag was chosen through a local design competition and adopted on 31 January 1968, the day Nauru became independent from its trusteeship. Its proportions are 1:2. The star can be confused with the stars on the flags of Australia and New Zealand, but those flags use multiple five- or seven-pointed stars and place them in different arrangements. Nauru's single twelve-pointed star is therefore highly distinctive.
