The Missing Piece is the ninth studio album by British progressive rock band Gentle Giant, released in 1977.

After the Interview tour this return to the studio marked a change of direction for the band with the first side of the album exploring different musical directions than the band was previously known for, including pop music and punk rock, while the second side was more in the vein of their signature progressive rock style.

The Unburied Treasure box set includes a replica of the uncompleted puzzle from the back cover of the album.

The Globe and Mail wrote that "Gentle Giant has become more listenable by becoming more commercial... With The Missing Piece, the band devours mainstream and burps up a polished bit of formula recording.

All tracks are written by Kerry Minnear, Derek Shulman, and Ray ShulmanThere are no official instrument credits listed on the album.
