Dr. Henry Walton "Indiana" Jones, Jr. is a fictional adventurer, OSS agent, professor of archaeology, and the protagonist of the Indiana Jones franchise. George Lucas created the character in homage to the action heroes of 1930s film serials. The character first appeared in the 1981 film Raiders of the Lost Ark, to be followed by Indiana Jones and the Temple of Doom in 1984, The Last Crusade in 1989, The Young Indiana Jones Chronicles from 1992 to 1996, and Kingdom of the Crystal Skull in 2008. Alongside the more widely known films and television programs, novels, comics, video games, and other media also feature the character. Jones is also featured in the theme park attraction Indiana Jones Adventure, which exists in similar forms at Disneyland and Tokyo DisneySea.

Jones is most famously played by Harrison Ford; he has also been portrayed by River Phoenix (as the young Jones in The Last Crusade), and in the television seriesThe Young Indiana Jones Chronicles by Corey Carrier, Sean Patrick Flanery, and George Hall. Doug Lee has supplied Jones's voice to two LucasArts video games, Indiana Jones and the Fate of Atlantis and Indiana Jones and the Infernal Machine, while David Esch supplied his voice to Indiana Jones and the Emperor's Tomb.

Particularly notable facets of the character include his iconic look (bullwhip, fedora, and leather jacket), wry sense of humor, deep knowledge of many ancient civilizations and languages, and fear of snakes.
