The name Joseline is of Spanish origin, derived from the masculine name José, which in turn comes from the Hebrew name Yosef. Yosef means "he will add" or "he will increase" in Hebrew. The name José was popularized by Portuguese explorers and missionaries during the 15th and 16th centuries, and it quickly spread throughout the Spanish-speaking world.

The feminine form Joseline emerged as a diminutive or pet name for José or Josefa. It was commonly used in Spain and Latin American countries like Mexico, Colombia, and Argentina. The earliest recorded instances of the name Joseline date back to the 17th century.

One of the earliest notable individuals with the name Joseline was Joseline de Artigas (1792-1868), the wife of Uruguayan revolutionary leader José Gervasio Artigas. She played a significant role in supporting her husband's struggle for independence from Spain.
