Flavio Gioia or Gioja, also known as Ioannes Gira Amalphensis (Italian pronunciation: [ˈflaːvjo ˈdʒɔːja]; c. 1300 – ?) is reputed to have been an Italian mariner, inventor, and supposedly a marine pilot. He has traditionally been credited with developing the sailor's compass, but this has been debated.
