"Moonlight Shadow" is a pop song written by British multi-instrumentalist Mike Oldfield and released as a single in May 1983 and included on the album Crises in the same year. The vocals were performed by the Scottish vocalist Maggie Reilly, who had joined Mike Oldfield in 1980. It has been his most successful single to date, with Tubular Bells being his most successful album worldwide. It is said that the lyrics were a reference to the death of John Lennon.

Numerous cover versions of "Moonlight Shadow" have been performed over the years, including by The Shadows (a band whom Oldfield was influenced by) on their 1986 album Moonlight Shadows. Notably Oldfield had also covered a Shadows song, "Wonderful Land".

A techno remix version was also released by DJ Mystik.
