The Lomaiviti (pronounced [lomaiˈβitʃi]) archipelago of Fiji consists of seven main islands and a number of smaller ones.

They cover a total area of 411 square kilometres (159 sq mi), and had a population of 15,657 at the most recent census in 2017.

The first known European sighting of the Lomaiviti Group was recorded in May 1789 by Captain William Bligh, who was on his epic voyage in a lifeboat to Timor having been cast adrift by his crew in the Mutiny on the Bounty.

The islands of Koro, Batiki, and Gau were seized by the United States Navy in 1867 as security for a long-standing debt owed to the United States consul John Brown Williams by Seru Epenisa Cakobau, the Vunivalu (Paramount Chief) of Bau Island who claimed to be King of Fiji.

This debt was one of the factors contributing to Cakobau's decision to cede Fiji to the United Kingdom in 1874, just three years after achieving his decades-long desire of uniting Fiji's myriad islands and tribes under his authority.
