The indigenous peoples of Nauru are an ethnicity, which inhabit the Pacific island of Nauru. They are most likely a blend of other Pacific peoples.

The origin of the Nauruan people has not yet been finally determined. It can possibly be explained by the last Malayo-Pacific human migration (c. 1200). It was probably seafaring or shipwrecked Polynesians or Melanesians, which established themselves there because there was not already an indigenous people present, whereas the Micronesians were already crossed with the Melanesians in this area.
