Robert Hood (1797–21 October 1821), born in Portarlington, Ireland, was an Anglo-Irish Royal Navy officer, explorer of the Canadian Arctic, and military artist.

[1] In 1819, Hood was appointed midshipman on the Coppermine expedition, where he, along with George Back, was an official artist.

In addition to documenting the expedition with watercolour paintings, he kept a journal which was used by John Franklin to complete his official account of the expedition, and recorded important meteorological, magnetic and auroral data.

[3][4] Hood was allegedly[5] murdered on 21 October 1821 by an Iroquois voyageur, Michel Terohaute,[6] who had supposedly turned to cannibalism, and who was summarily executed by John Richardson a few days later.

Hood's promotion to lieutenant came in January 1821, the news of which did not reach the party until 15 December 1821.
