Gloria is a female given name which comes from the Latin word glōria meaning “glory, renown, fame”, used in praise, exaltation, or great honor of someone or something by common consent. It’s background is of obscure/uncertain origin; it may be related to Old Latin *gnōria (knowledge, fame) via PIE root word *ǵneh₃- (to know).

Gloria is also used in a religious sense, the name of several Christian liturgical hymns in praise of God, so it also connotes a sense of “divine glory”.

Gloria is also a Spanish, Portuguese, and Italian surname which originated either a matronymic name or as an occupational name for a singer, in reference to the hymn Gloria in excelsis Deo (“Glory to God in the highest”).
