Annia is a feminine given name of Latin origin, derived from the name Anna, which means "grace" or "favor". It was popularized by the Roman Emperor Nero's mother, Agrippina Minor, who was known as Julia Agrippina Anniana after her father. The name has been used throughout history and across various cultures, with notable bearers including Annia Cerrini, an Italian actress, and Annia Hatch, an American poet. It is typically spelled with two 'n's but can also appear as Anna or Annia in some cases.
The name Annia experienced significant fluctuations in popularity over the years, with several periods of no recorded births and others with notable spikes.
