A Voyage Round the World is Georg Forster's report on the second voyage of the British explorer James Cook. During the preparations for Cook's voyage, the expedition's naturalist Joseph Banks had withdrawn his participation, and Georg's father, Johann Reinhold Forster, had taken his place at very short notice, with his seventeen-year-old son as his assistant. They sailed on HMS Resolution with Cook, accompanied by HMS Adventure under Tobias Furneaux. On the voyage, they circumnavigated the world, crossed the Antarctic Circle and sailed as far south as 71° 10′, discovered several Pacific islands, encountered diverse cultures and described many species of plants and animals.

Johann George Adam Forster, also known as Georg Forster, was a German geographer, naturalist, ethnologist, travel writer, journalist and revolutionary. At an early age, he accompanied his father, Johann Reinhold Forster, on several scientific expeditions, including James Cook's second voyage to the Pacific. His report of that journey, A Voyage Round the World, contributed significantly to the ethnology of the people of Polynesia and remains a respected work. As a result of the report, Forster, who was admitted to the Royal Society at the early age of twenty-two, came to be considered one of the founders of modern scientific travel literature.
