Tommaso Raggio (Latin: Thomas Razzius) (1531–1599) was a 16th century Jesuit missionary. Raggio joined Jesuit order in 1557 in Loreto. Raggio was Catholic missionary in Kotor in 1574–75. Raggio was a poliglot who knew six foreign languages, including Croatian. According to Miroslav Vanino, Raggio learned Croatian language in Kotor so he later worked for the benefit of Croats and other Balkan people. Raggio emphasized that Jesuit presence in Kotor is very important because Kotor was very near Serbia while Kotor Bay goes deep into the territory populated with Orthodox people.
