Henry McNish, often referred to as Harry McNish or by the nickname Chippy, was the carpenter on Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition of 1914–1917. He was responsible for much of the work that ensured the crew's survival after their ship, the Endurance, was destroyed when it became trapped in pack ice in the Weddell Sea. He modified the small boat, James Caird, that allowed Shackleton and five men to make a voyage of hundreds of miles to fetch help for the rest of the crew.

Sir Ernest Henry Shackleton was an Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.
