What it means
Latin felix, 'lucky, fortunate, prosperous.' A standard Roman cognomen, and the name of four popes and dozens of saints. Felix the Cat made it the cartoon name of the early 20th century.
Felix is the Latin word for 'lucky, fortunate, prosperous,' used as a Roman cognomen (Sulla Felix, Antoninus Felix). Four popes took the name; Felix of Nola and Felix of Cantalice are among many saints. Felix the Cat (the silent-film and early-sound cartoon character from 1919) gave the name 20th-century pop-culture anchor. Felix Mendelssohn (composer), Felix Frankfurter (Supreme Court justice), and Felix Baumgartner (the 2012 Red Bull stratosphere jump) are the modern historical anchors. The name has surged in the US since 2015, particularly in families looking for one-word European names with built-in optimism. Rarely shortens.
