The name Julieta is derived from the Latin name Julia, which was a feminine form of the name Julius. The name Julius originated from an ancient Roman family, known as the Julii. This family traced their roots back to the mythological figure Iulus, the son of Aeneas in Roman mythology.

Julieta is the Spanish and Portuguese variant of the name Julia. It gained popularity in Spain and Portugal during the Middle Ages, particularly after the famous play "Romeo and Juliet" by William Shakespeare was translated into these languages.

One of the earliest recorded instances of the name Julieta can be found in the 13th-century Spanish literary work "El Libro de Buen Amor" (The Book of Good Love) by Juan Ruiz, Arcipreste de Hita. In this work, a character named Julieta is mentioned.
