Guadalcanal Province is one of the provinces of the Solomon Islands, consisting of the island of Guadalcanal. It is a 2,510 square mile (5,336 km²) island and is largely a jungle. Its name was given by Pedro de Ortega Valencia, born in the village of Guadalcanal, Seville, Spain. The national capital and largest city of the Solomon Islands, Honiara, is on the island; however, in July 1983 it was designated a 22-km² separately-administered Capital Territory and is no longer considered part of the province. The population of the province is 93,613 (2009), not including the capital territory. The population of the island (including Honiara) is 109,382 (1999). Honiara serves as the provincial capital. This province and Malaita Province started to use Korean hangul in October 2012 for the written form of their tribal language.
