Lucia of Syracuse (283–304), also called Saint Lucia (Latin: Sancta Lucia) better known as Saint Lucy, was a Roman Christian martyr who died during the Diocletianic Persecution. She is venerated as a saint in the Catholic, Anglican, Lutheran, and Eastern Orthodox churches.

No, they are distinct entities, though their names are etymologically linked. Saint Lucy (Santa Lucia) refers to the 4th-century Roman Christian martyr from Syracuse, Sicily, who is the patron saint of the blind and is celebrated with festivals of light on December 13th. In contrast, Saint Lucia is a sovereign island nation in the Caribbean. While the country was named in honor of the saint (reportedly by French sailors shipwrecked there on her feast day), "St Lucy" usually refers to the historical figure or specific parishes (like St. Lucy, Barbados), whereas "St Lucia" refers to the tropical country known for the Pitons.
