Calamity, of Latin origin, is an uncommon given name that translates to 'sudden disaster' or 'great misfortune'. It's derived from the word 'calamity', which first appeared in English in the late 14th century. Historically, this name has been more frequently used as a nickname than as a true given name. In popular culture, it is most notably associated with Calamity Jane, an American frontierswoman and scout who gained fame for her exploits during the late 19th century.
