Henry Worsley, English colonel and explorer (b. 1960)
Lieutenant Colonel Alastair Edward Henry Worsley, (4 October 1960 – 24 January 2016) was a British explorer and British Army officer. He was part of the successful 2009 expedition that retraced Ernest Shackleton's footsteps in the Antarctic.

Worsley died in 2016 while attempting to complete the first solo and unaided crossing of the Antarctic. Attempting to be the first person to cross Antarctica on foot, unassisted and unsupported, he crossed more than 900 miles (1450 km) and was forced, by exhaustion and ill health, to call for help 126 miles (200 km) from his journey's intended end. Rescued and flown to a hospital in Punta Arenas, in the Patagonia region of southern Chile, he was given a diagnosis of peritonitis, and died. He was 55.
