Sir Henry William Gore-Booth, 5th Baronet (1 July 1843 – 13 January 1900), was a notable Arctic explorer, adventurer and landowner from Lissadell House, Sligo, Ireland.
The Gore Baronetcy, of Artarman in the County of Sligo, was created in the Baronetage of Ireland on 30 August 1760 for Booth Gore. His father, Sir Robert Gore-Booth, 4th Baronet was an Anglo-Irish landowner who according to some sources was accused of evicting his starving tenant farmers during the period of the Great Irish famine and of packing them into coffin ships to emigrate. In contrast, other reports state that he mortgaged his estates and assisted his tenants by both providing them with food and refusing to accept any rents during the famine.
Sir Henry, enjoyed a much better relationship with the tenants on his 32,000 acre (12,950 ha) estate and he was seen as a "progressive landlord". Sir Henry was not involved in public affairs and was interested in the development of his estate, the welfare of his tenants and served both as the president of the Sligo Agricultural Society and the chairman of the Sligo, Leitrim and Northern Counties Railway. He was appointed High Sheriff of Sligo for 1872, and was a Deputy Lieutenant and Justice of the Peace for Sligo.
During his Arctic expeditions, Sir Henry was involved in the rescue of a fellow Arctic explorer called Benjamin Leigh Smith in 1882. Sir Henry was also a prolific writer on a variety of topics including Arctic exploration, yachting, whaling, polar bear hunting and shark fishing. He sailed his own yacht to the Arctic. He also hunted big game in Africa.
