The album era was a period in popular music during the latter half of the 20th century in which the physical album was the dominant form of recorded music expression and consumption. Usually defined as lasting from the mid-1960s until the mid-2000s, it was driven primarily by three successive music recording formats: the 33⅓ rpm long-playing record (LP), the cassette tape, and the compact disc (CD). Rock musicians from the US and UK were often at the forefront of the era, which is sometimes called the album-rock era in reference to their sphere of influence and activity. The term "album era" is also used to refer to the marketing and aesthetic period surrounding a recording artist's album release.

An album is a collection of audio recordings issued on a medium such as compact disc (CD), vinyl (record), audio tape, or digital. Albums of recorded sound were developed in the early 20th century as individual 78 rpm records collected in a bound book resembling a photo album; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33+1⁄3 rpm.
