Meaning and origin of Cleo
Cleo is a Greek name that means “glory of the father”.
Cleo is a short form of Cleopatra, a Greek name meaning glory of the father. Cleopatra was borne by several queens of the Ptolemaic dynasty in Egypt, most famously Cleopatra VII, the last active ruler of that kingdom, whose story has been retold by Shakespeare and countless others. Cleo has stood on its own as a given name for well over a century. It is compact, stylish and slightly vintage, fitting alongside names like Iris and Stella. Some parents also link it with Clio, the Greek muse of history, which has a similar sound.
