Angel's Egg is the fourth studio album by the progressive rock band Gong, released on Virgin Records in December 1973.

It was recorded using the Manor Mobile studio at Gong's communal home, Pavillon du Hay, Voisines, France, and mixed at The Manor, Oxfordshire, England. The album was produced by "Gong under the direction of Giorgio Gomelsky".

Angel's Egg is the second in Gong's Radio Gnome Invisible trilogy of albums, following Flying Teapot and preceding You. The trilogy forms a central part of the Gong mythology. The original album did not have an apostrophe in the title.

The original vinyl edition came with a booklet containing an extensive explanation of the mythology, including lyrics, a glossary of terms, and profiles of characters in the story and band members. This edition also had a gatefold cover (omitted in later pressings), a plain inky blue inner sleeve to match the gate fold and booklet, and had the original black and white Virgin label which was discontinued after 1973; it was one of the last albums to use the original label. Some copies had a sticker over top of the female nude in the moon on the cover.

The CD version released by Virgin Records, and later reissued on Charly Records contains an extra track: "Ooby-Scooby Doomsday or The D-day DJs Got the D.D.T. Blues", that ends with a male voice choir glissando (questionably regarded by some as a parody on Pink Floyd's "Echoes"), starting with "Ahhhh" and ending with "Chooo", mimicking a sneeze. The track was originally released on the Live Etc. album but was excluded from the CD release (which reissued that double album as one disc), and included on this album instead.

A half speed master cut at Abbey Road by Miles Showell using the 2018 96k24bit files was released in the UK on 180 gram vinyl for Record Store Day on 22 April 2023 to mark the album’s 50th anniversary. This release was in a gatefold sleeve with a replica of the original 16-page Blue Book of lyrics and drawings plus an Abbey Road Certificate.
