Kaibu Island Airport (ICAO: NFKB) is a small, remote airstrip located on Kaibu Island in the Lau Group of Fiji. It serves as a basic landing facility for light aircraft connecting the island to other parts of Fiji, primarily for private, charter, and occasional inter-island service. The airstrip is typical of remote Fijian island facilities, featuring a grass or unpaved runway and minimal infrastructure. It supports access to what is largely a privately held and sparsely populated island in eastern Fiji. Given its remote location and limited traffic, the airport has no scheduled commercial airline services and functions primarily to support private access to the island.
