The Wall is a rock opera and concept album by Pink Floyd. Hailed by critics and fans as one of Pink Floyd's best albums (along with Dark Side of the Moon, Wish You Were Here, and Animals), the album is known as a rock and roll classic, and its morbid, depressing anthems have inspired many contemporary rock musicians. This was the last studio Pink Floyd album to feature Richard Wright until his return in 1987.

Roger Waters was inspired to create the album during a 1977 concert tour for Animals, dubbed Pink Floyd — In the Flesh. In Montreal, a fan's disruptive behaviour resulted in Waters spitting in the fan's face. Immediately disgusted with himself, Waters's alienation by his fans urged him to build a wall between himself and the audience, an idea which later evolved into the album.

All of the songs were penned by Roger Waters with the exceptions of "Young Lust", "Comfortably Numb" and "Run Like Hell," which were co-written by David Gilmour, and "The Trial", which was co-written by Bob Ezrin.

The album has been certified 23 times platinum and hit #1 on the Billboard Album Charts in 1980. Originally released on Columbia Records in the US and Harvest Records in the UK, The Wall was then re-released as a digitally remastered CD in 1994 in the UK on EMI. Columbia issued the remastered CD in 1997 in the US and rest of the world. For The Wall's 20th Anniversary in early 2000, Capitol Records in the US and EMI for the rest of the world re-released the 1997 remastered CD.

In 1998 Q magazine readers voted The Wall the 65th greatest album of all time and in a similar poll in 2003, Rolling Stone magazine readers named it the 87th greatest album of all time.
