"Cuckoo Song" is a musical piece written by Michael Praetorius (1571 – 1621).

In 1977 British musician Mike Oldfield released an arrangement of the piece as a single.

Mike Oldfield released a version of "Cuckoo Song" in 1977 as a non-album single on Virgin Records.

The B side, a musical precursor of Incantations and which could almost be a part of it, is an original composition by Oldfield.

The single (in a plain white sleeve) was included as a free bonus when the double LP Incantations was released in 1978.
