Era (styled as +eRa+) is a new-age music project by French composer Eric Lévi. Some of the lyrics were written by Guy Protheroe in an imaginary language similar to Latin, but deliberately devoid of any exact meaning. Musically, the project blends Gregorian chants with modern elements and genres, especially rock, pop and electronic music.

Era’s first album, Era, was released in 1996 and became a worldwide success, helped by its first single, "Ameno". It sold over 6 million copies and became the most exported French album at the time. It was followed by Era 2 in 2000 and The Mass in 2003. In 2008, the project saw a significant departure from its previous themes and presented a more electronic soundscape with Arabic influences in its fourth album, Reborn. In the following two years, Era released Classics and Classics 2, which consisted in contemporary reinterpretations of classical works by Johann Sebastian Bach, Giuseppe Verdi, Antonio Vivaldi, Wolfgang Amadeus Mozart, Ludwig van Beethoven and Pyotr Ilyich Tchaikovsky, amongst others. In 2013, Era released an album in collaboration with French singer and actress Arielle Dombasle titled Arielle Dombasle by Era. Era's last album was released in 2017, The 7th Sword.
