Thomas Grant Hadwin (born October 25, 1949) was a Canadian forest engineer. In January 1997, he felled Kiidk'yaas (also known as "the Golden Spruce"), a Sitka Spruce tree located on the Haida Gwaii archipelago and considered sacred by the Haida people. Hadwin stated that he cut the tree down as a protest against the logging industry. While facing criminal charges for the act, he disappeared en route to his trial. His fate remains unknown.
