A compilation album comprises tracks which are compiled from other recordings, usually previously released, but sometimes unreleased. The tracks may be from one or several performers; if from several performers there may be a theme, topic or genre which links the tracks. When the tracks are by the same recording artist, the album may be referred to as a retrospective album. Compilation albums may employ traditional product bundling strategies.

Compilation may refer to:

• In computer programming, the translation of source code into object code by a compiler
  • Compilation error
  • Compilation unit
• Product bundling, a marketing strategy used to sell multiple products
• Compilation thesis
