George Campbell Munro (10 May 1866 – 4 December 1963) was a New Zealand born pioneer of Hawaiian botany and ornithology.
He settled on a ranch in Lanai and wrote one of the first books on the birds of Hawaii, many species of which are now extinct.
Munro was born in New Zealand, but little is known of his early life other than that he was a gumdigger collecting kauri tree resin for the varnish industry.
After a brief visit to New Zealand in 1911 he returned to manage Dole Company’s Lana‘i cattle ranch.
He introduced Cook Island pine trees after noting that they condensed fog and dripped them onto the land.
