Circumnavigation is the complete navigation around an entire island, continent, or astronomical body. This article focuses on the circumnavigation of Earth.

Joshua Slocum was the first person to sail single-handedly around the world. He was a Nova Scotian-born, naturalised American seaman and adventurer, and a noted writer. In 1900 he wrote a book about his journey, Sailing Alone Around the World, which became an international best-seller. He disappeared in November 1909 while aboard his boat, the Spray.
