Thomas Gibson Nickerson (March 20, 1805 – February 7, 1883) was an American sailor and author. In 1819, when he was fourteen years old, Nickerson served as cabin boy on the whaleship Essex. On this voyage, the ship was sunk by a whale it was pursuing, and the crew spent three months at sea before the survivors were rescued. In 1876 he wrote The Loss of the Ship "Essex", an account of the ordeal and of his subsequent experiences at sea. The manuscript was lost until 1960, and was first published in 1984.
