Graham Gore (c. 1809 – between 28 May 1847 and 25 April 1848) was an English officer of the Royal Navy and polar explorer who participated in two expeditions to the Arctic and a survey of the coastline of Australia aboard HMS Beagle. In 1845 he served under Sir John Franklin as First Lieutenant (the third most senior rank) on the Erebus during the Franklin expedition to discover the Northwest Passage, which ended with the loss of all 129 officers and crewmen in mysterious circumstances.
