Renatus is a first name of Latin origin which means "born again" (natus = born). In countries of Italian, Portuguese and Spanish languages it exists in a masculine and feminine form i.e., Renato and Renata. In the French language they have been translated to René and Renée. The feminine form Renate is also common in Norwegian, Dutch and German language-speaking countries. Renata is a common female name in Poland, Czech Republic, Croatia, Lithuania and Slovakia. In Russia the names Renat (Russian: Ренат) (sometimes Rinat) and Renata (Russian: Рената) are widespread among the Tatar population. In some Spanish speaking countries, the name has taken on a different meaning: as a contraction for Rey (king) and Nato (birth), it has come to mean "born a king."
The name has a spiritual, not literal meaning, i.e., to be born again with baptism, i.e., from water and the Holy Spirit. It was extensively adopted by early Christians in Ancient Rome, due to the importance of baptism. The onomastic is Saint Renatus, a martyr, Bishop of Sorrento in the 5th century, which is celebrated on October 6.
