Lee was born to parents John Lee, a disc jockey and TV personality, and Sara Cargill. She has one brother, Robby, and two sisters, Carrie and Lori. Lee had a third sister, who died in 1987 at the age of three from an unidentified illness. The song "Hello" from Fallen has been reported to have been written for her late sister, as well as the song "Like You" from The Open Door with the lyrics, "I long to be like you, sis; Lie cold in the ground like you, did," also hinting at the death of her sister and her grief for it. Lee took classical piano lessons for nine years. Her family moved to many places, including Florida and Illinois, but finally settled in Little Rock, Arkansas, where Evanescence started. She graduated from Pulaski Academy in 2000 and also briefly attended Middle Tennessee State University. Lee has stated that she is of mostly Scottish and English heritage.

In an interview on AOL Music, Lee revealed that the first songs she remembered writing were called "Eternity of the Remorse" and "A Single Tear". The first was written when she was eleven years old and wanted to become a classical composer, and the second was for an assignment when she was in the eighth grade.

She co-founded the band with Ben Moody. The two met at a youth camp after he heard Lee playing Meat Loaf's "I'd Do Anything for Love (But I Won't Do That)" on the piano. Within a month, the pair were playing acoustic sets at Arkansas book stores and coffee houses, and they eventually recorded two EPs, Evanescence EP (1998) and Sound Asleep EP (1999), selling them at various local venues. In 2000, Evanescence recorded the longer EP Origin. This demo contains three songs from the debut album Fallen and was written by Lee and Moody: "Whisper", "Imaginary" and "My Immortal". Whereas "Whisper" and "Imaginary" underwent further modifications before being included on Fallen, "My Immortal" is virtually identical. A later band version of "My Immortal" was made available for download for those who had bought an official version of Fallen through their official web site, but required that a CD checker program also be downloaded for verification before it would play.[ The band version was included on later copies of Fallen, notably the Brazilian and Argentinian editions.

On October 22, 2003, guitarist Ben Moody left the band citing "creative differences". In an interview several months later, Amy said: "We'd gotten to a point that if something didn't change, we wouldn't have been able to make a second record". She also said "We're finally a real band, not just Ben and I and a few others thrown together". Ex-Cold guitarist Terry Balsamo replaced Moody in the band, both on guitar and as Lee's writing partner.

On December 1, 2005, former Evanescence manager Dennis Rider filed a lawsuit against Lee for breach of contract. The suit claims Rider was prematurely and unjustly terminated from his position as manager of Evanescence.

In return, Lee filed a counter-suit against Rider for "breach of fiduciary duty, sexual assault and battery, professional negligence, currency conversion, and other charges". The suit also claims Rider "neglected Lee's career and business and has focused his efforts on having extramarital affairs, hiding them from his wife, becoming intoxicated during business meetings, physically abusing women and boasting about it, making repeated unwelcome sexual advances toward Lee, receiving fees in excess of what was provided for in his management agreement and using Lee's corporate credit card to purchase gifts for his mistress."

Rider's attorney, Bert Deixler, claimed in a statement that Rider had fully performed all of the duties and obligations owed by the firm under the management agreement, and that he had always conducted himself by the highest professional standards.
