Celia is a given name for females of Latin origin, as well as a nickname for Cecilia, Celeste, or Celestina. The name is often derived from the Roman family name Caelius, thought to originate in the Latin caelum (“heaven”). As a derivative of Cecilia, Celia can also mean “musical”.
Shakespeare used it in his play ‘As You Like It’ (1599), which introduced the name to the English-speaking public. It is sometimes used as a short form of CECILIA.
