Jesse Martin, OAM (born 26 August 1981) is a German-Australian sailor who in 1999 became the youngest person to circumnavigate the globe solo, non-stop, and unassisted, taking the record from David Dicks, who was 24 days younger when he completed his circumnavigation, but had obtained assistance.
Martin's journey in the 34-foot (10 m) S&S 34 sloop Lionheart-Mistral took approximately 11 months.
He chronicled his adventures in the book Lionheart: A Journey of the Human Spirit, and his story was made into a documentary, Lionheart: The Jesse Martin Story.
