The Kon-Tiki expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl.

The raft was named Kon-Tiki after the Inca god Viracocha, for whom “Kon-Tiki” was said to be an old name. Kon-Tiki is also the name of Heyerdahl’s book, the Academy Award–winning 1950 documentary film chronicling his adventures, and the 2012 dramatized feature film nominated for the Academy Award for Best Foreign Language Film.
