"There Must Be an Angel (Playing with My Heart)" is a 1985 song written and performed by the British musical duo Eurythmics. Released as the second single from their fifth album Be Yourself Tonight, the song features a harmonica solo by the American musician Stevie Wonder. The song became a worldwide success; most notably in Ireland, Norway and the United Kingdom, where it became the duo's only chart-topping single to date.

Ever since the record has been covered by several musical artists, including Brittany Murphy, Fantastic Plastic Machine, Leningrad Cowboys, Luciano Pavarotti, Kylie Minogue, Jessica G. Pilnäs and, most noticeably, German pop group No Angels who scored their second number-one hit in Austria and Germany with their interpretation for the reissue of their album Elle'ments in August 2001.

Upon its release, "There Must Be an Angel (Playing with My Heart)" became Eurythmics' first (and to date only) number-one single in the UK, also topping the charts in Ireland, Norway and Brazil. While the song peaked at number 22 on the US Billboard Hot 100, it became another Top 10 success for the band in Sweden, Belgium, the Netherlands, Germany, France, Austria and Australia.
