"Hero" is a song by American singer-songwriter, and record producer Mariah Carey released on October 18, 1993, via Columbia Records as the second single from her third studio album, Music Box (1993).
The song was originally recorded by Gloria Estefan. The song was written and produced by Carey and Walter Afanasieff. While writing the song, Carey did not connect to its style or sound, therefore forfeiting it over to Estefan who sang it for the soundtrack of the film of the same name (1992).
However, after being convinced by Sony executive Tommy Mottola to keep it, she changed some of the lyrics to more precisely fit her personality. Lyrically, the song is regarded as one of Carey's most inspirational and personal ballads, with its protagonist declaring that even though people may feel discouraged or down at times, in reality, they are "heroes" if they look inside themselves and see their own inner strength; in time, it will help them "find the way".
The song received mixed reviews from contemporary music critics for its lyrical content, while Carey's vocal performance was praised. Aside from its lyrics, "Hero" derived its hook and sound from several musical instruments such as the guitar, piano, and organ.
The song was a global success, reaching the top five in Canada, France, Ireland, New Zealand and Norway, the top ten in Australia, the United Kingdom, and becoming Carey's eighth chart topper on the US Billboard Hot 100. Additionally, it was ranked number 53 on the Decade-End Chart.
Due to fan requests and letters, as well as their connection to its personal meaning and content, the song remains one of Carey's most performed songs. Deemed by many as her signature song, the song was originally performed on The Arsenio Hall Show, The Tonight Show with Jay Leno, and Hey Hey It's Saturday during its original chart run. Additionally, Carey has performed Hero at several special live telethons, memorials and benefit concerts; in 1996, Mariah sang the song at Capitol Hill’s Peace Officers Memorial Day service in Washington, D.C. (with the Clinton family in attendance), as well as Pavarotti and Friends in 1998, Michael Jackson & Friends in 1999, America: A Tribute to Heroes in 2001, Live 8 in 2005, and the inaugural ball for Barack Obama in 2009. Additionally, the song has been featured on all of Carey's tours, usually serving as the encore or closing number, and making its debut during the album's accompanying set of concerts, the Music Box Tour. The song was included on several of Carey's compilation albums, #1's (1998), Greatest Hits (2001), The Ballads (2008), and #1 to Infinity (2015).
Throughout the course of her career, Carey has re-recorded the song twice, and filmed other music videos, aside from the original. The first music video for the song was filmed by Larry Jordan in July 1993, during a private concert at Proctor's Theatre, later released on the home video Here Is Mariah Carey. In 2001, following the September 11 attacks, Carey re-recorded the song as a mash-up single titled "Never Too Far/Hero Medley", a medley with her single at the time, "Never Too Far".
Additionally, prior to the release of her compilation album The Ballads, Carey re-recorded "Hero" and filmed a new video featuring behind the scenes footage of the studio. "Hero" won two ASCAP Rhythm & Soul Music Awards, one ASCAP Pop Music Award and one BMI Pop Award for the Songwriter Award.
The song has been covered many times during both studio and live recordings, such as on global singing competitions.
