"Hand on Your Heart" is a song written and produced by Stock Aitken Waterman.

Recorded by Kylie Minogue it was released in April 1989 in the UK as the lead single from her second album, "Enjoy Yourself".

The song became Minogue's third song to debut at number two on the UK Singles Chart, before it peaked at number one the following week. On its third week it was replaced on the top of the chart by the UK Hillsborough disaster charity single "Ferry Cross the Mersey" by The Christians, Holly Johnson, Paul McCartney, Gerry Marsden and Stock, Aitken and Waterman. 

The song was one of the first singles to sell well on cassette, selling 11,000 copies in the first week of release. This would have been enough to have Minogue enter in at number one, something no female had ever done at the time. However, PWL issued the cassette single at a cut price of £1.99, which was cheaper than chart regulations at the time allowed. This meant The Bangles stayed at number one with "Eternal Flame", with around 1,600 more sales. Because of this the rules were quickly changed so that cut-price cassette singles were allowed. The market for cassette singles stood at 0.5% at the time and the BPI hoped to encourage growth of the cassette single.

Outside of the UK, the song was also successful. It reached number 4 in Australia and became Minogue's fifth top 5 single on the singles chart. In reached the top 10 in Denmark, Finland, France, Japan, and South Africa, and the top 20 in Germany, the Netherlands, New Zealand and Sweden.
