"Total Eclipse of the Heart" is a song recorded by Welsh singer Bonnie Tyler. It was written and produced by Jim Steinman, and released in 1983.

The song became Tyler's biggest career hit, topping the UK Singles Chart, and becoming the fifth-best-selling single in 1983 in the United Kingdom. In the United States, the single spent four weeks at the top of the charts, and was Billboard's number-six song of the year for 1983. 

Worldwide, the single has sales in excess of 6 million copies.

Nicki French released a Hi-NRG remake of "Total Eclipse of the Heart" in 1995, which was also a worldwide hit. It originally peaked at No. 54 on the UK Singles Chart in 1994, but reached No. 5 after being re-issued in 1995. In the United States, French's version peaked at No. 2 on the Billboard Hot 100, behind "Have You Ever Really Loved a Woman?" by Bryan Adams and it garnered frequent airplay on AC radio. It enjoyed greater success in Australia, spending four nonconsecutive weeks at No. 2 behind "Here's Johnny!" by Hocus Pocus. Elsewhere, the cover reached number 13 in New Zealand, number 16 in Canada, and peaked within the top 10 of several European countries.

French had made her first dance version recording of "Total Eclipse of the Heart" in 1994: she had purchased the Bonnie Tyler original as a teenager in 1983 and reacted negatively to the original suggestion that she (i.e. French) remake the song as dance track — "I thought, no, it's too strong a song to go down the dance route. You know, it demeans it almost. But then I thought well, I'll give it a go. And as soon as I heard the track, I thought it actually does work." The singer had been performing in London bands since the age of 12 and was given the chance to record a version when she received a phone call from a fellow British musician. French's first recording of "Total Eclipse of the Heart", made with John Springate of the Glitter Band producing, came to the attention of Mike Stock and Matt Aitken who produced their own recording of the song by French and it was this version which appeared on the UK chart dated 15 October 1994 at No. 54. French would recall: "I just thought oh well that was great...I've [worked with] Mike Stock and Matt Aitken and it was a dream come true...we tried and I had a great time...And then about two months later I had a call out of the blue from Mike saying the buzz will not die down on this track so we're going to re-record the beginning...and we're going to re-release it at the beginning of 1995."

According to French, her remake of "Total Eclipse of the Heart" became popular in the UK and the US in distinct remixes: "the slower version was the one that actually took a hold in the UK where originally they started with the fast one and then decided to go with the [remix which began] in the same vein as the Bonnie Tyler version [and then] sped up when the chorus came in...In the US it was the [remix] which was fast all the way through."
