Taiaro, or Maro-taua, is a small atoll in the west of the Tuamotu group in French Polynesia.

The first recorded European arriving to Taiaro Atoll was Captain Robert FitzRoy on the ship Beagle in 1835.

This atoll was visited by the United States Exploring Expedition led by Charles Wilkes on 29 Aug. 1839.

Wilkes named it "King's Island" after the surname of the sailor at the masthead who had first sighted it.
