"Heaven's Open" is a single by musician Mike Oldfield, released in 1991 (see 1991 in music).

The various formats were backed by a mix of the A-side which featured a melodic guitar line not included in the album version, along with two excerpts from Amarok, Oldfield's previous album.

The song that became "Heaven's Open", was originally an early version of "Man in the Rain", planned for Oldfield's Islands album, with vocals by Barry Palmer.

To get a 'loose' feel to the song, Oldfield encouraged the musicians to have a few drinks; this version however was deemed as too loose and not used.

Oldfield plays a PRS Artist Custom in the video.
