New Georgia Sound is the sound in the New Georgia Islands region that runs approximately east/west through the middle of the Solomon Islands in the Southern Pacific Ocean and Melanesia.
The sound is bounded by Choiseul Island, Santa Isabel Island, and Florida Island to the north, and by Vella Lavella, Kolombangara, New Georgia, and the Russell Islands to the south. Bougainville Island of the Autonomous Region of Bougainville (Papua New Guinea) and Guadalcanal island, define western and eastern ends of the sound, respectively.
It is one of three major routes for merchant shipping through the Solomon Islands archipelago. The 2 others are: the Bougainville Strait and Indispensable Strait route which links the Pacific Ocean, Solomon Sea and Coral Sea; and the Manning Strait route, which links the Pacific to New Georgia Sound.
Savo Island, a volcanic cone northwest of Guadalcanal, is a topographically significant island in the eastern region.
Captain Edward Manning sailed Pitt through the sound in 1792, on his way to Bengal in British India after having delivered convicts to Port Jackson in New South Wales, colonial Australia.
