Aja ( /ˈeɪʒə/, pronounced like Asia) is the sixth album by the jazz rock band Steely Dan. Originally released in 1977 on ABC Records, it became the group's best-selling album. Peaking at No. 3 on the U.S. charts and No. 5 in the United Kingdom, it was the band's first platinum album, eventually selling over 5 million copies^{[citation needed]}. In July 1978, the album won the Grammy Award for Best Engineered Non-Classical Recording. In 2003, the album was ranked number 145 on Rolling Stone's "The 500 Greatest Albums of All Time" list.

Donald Fagen has said the title of the album comes from the name of a Korean woman who married the brother of a high-school friend of his. The cover photo by Hideki Fujii features Japanese model/actress Sayoko Yamaguchi.

The album features several leading session musicians. The eight-minute-long title track features jazz-based changes and a solo by saxophonist Wayne Shorter.

Aja is the subject of one of the Classic Albums, a series of documentaries about the making of famous albums. The documentary includes a song-by-song study of the album (the only omission being "I Got the News," which is played during the closing credits), interviews with Steely Dan co-founders Walter Becker and Donald Fagen (among others) plus new, live-in-studio versions of songs from the album. Becker and Fagen also play back several of the rejected guitar solos for "Peg," which were recorded before Jay Graydon produced the satisfactory take.

An album may be understood as a collection of recordings, released as a single package on gramophone record, cassette, compact disc, or via digital distribution, however the concept is found in printed music dating into the early nineteenth century in works by composers such as Schumann and Mendelssohn. The word derives from the Latin word for list.

Today, with the vinyl record no longer being used as the primary form of distribution, the term "album" can still be applied to any sound recording collection, such as those on compact disc, MiniDisc, Compact audio cassette, and digital or MP3 albums.Cover art is also considered an integral part of the album. Many albums also come with liner notes and inserts giving background information or analysis of the recording, reprinted lyrics, images of the performers, or additional artwork and text. These are now often found in the form of CD booklets.

Vinyl LP records have two sides, each comprising one half of the album. If a pop or rock album contained tracks released separately as commercial singles, these were often traditionally placed in particular positions on the album. A common configuration was to have the album led off by the second and third singles, followed by a ballad. The first single would lead off side 2. In the past many singles (such as the Beatles' "Hey Jude" and Bob Dylan's "Positively 4th Street") did not appear on albums, but others (such as the Beatles' "Come Together" and Dylan's "Like a Rolling Stone") were part of an album released concurrently. Today, many commercial albums of music tracks feature one or more singles, which are released separately to radio, TV or the Internet as a way of promoting the album. Albums have also been issued that are compilations of older tracks not originally released together, such as singles not originally found on albums, b-sides of singles, or unfinished "demo" recordings.
