"Moonlight Shadow" is a song written and performed by English multi-instrumentalist Mike Oldfield, released as a single in May 1983 by Virgin Records, and included in the album Crises of the same year. The vocals were performed by Scottish vocalist Maggie Reilly, who had been collaborating with Mike Oldfield since 1980. It is Oldfield's most successful single, reaching number one on a number of charts around Europe.

The single peaked at number 4 in the British charts, making it Oldfield's second highest ranked single after "Portsmouth", which reached number 3 in 1976. "Moonlight Shadow" was successful throughout Europe. It reached number 1 in many countries, including Italy, Austria, Switzerland for four weeks and Norway for six weeks. It spent four weeks at number 2 in Germany, hit number 6 in Australia, and peaked at number 3 in New Zealand and France. It was re-released as a maxi-CD single in 1993 to promote Oldfield's Elements box set, charting at number 52.

A 12-inch single (later reissued on a 3" CD single) featured an extended version of the song with an extra verse, and the single B-side was "Rite of Man", which was a rare instance of Oldfield singing lead vocal. The extended mix also appears on his compilation album The Platinum Collection.
