The first solo circumnavigation of the globe is completed by Joshua Slocum from Briar Island, Nova Scotia.

Joshua Slocum (February 20, 1844 on or shortly after November 14, 1909) 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.

Circumnavigation is the complete navigation around an entire island, continent, or astronomical body (e.g. a planet or moon). This article focuses on the circumnavigation of Earth.

The first recorded circumnavigation of the Earth was the Magellan-Elcano expedition, which sailed from Sanlucar de Barrameda, Spain in 1519 and returned in 1522, after crossing the Atlantic, Pacific, and Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth is straightforward, usually taking days instead of years. Today, the challenge of circumnavigating Earth has shifted towards human and technological endurance, speed, and less conventional methods.
