Timeline is the second compilation album by Dutch progressive metal project Ayreon. It was released in November 2008 in Europe. It was also released in North America in early 2009. The album features three CDs containing selected songs from all Ayreon albums, and a DVD featuring live performances, video clips and behind-the-scenes.
The third CD also features a song, called "Epilogue: The Memory Remains", specifically written for the release, which provides further insight into the final chapter of the Ayreon concept and the probable future of its characters. Jasper Steverlinck, singer of Arid, made a guest appearance as the vocalist of the song. He would later be invited by Arjen to sing on his new side project Guilt Machine.
Many songs were remastered for this release. Apart from the CDs and DVD, a timeline poster illustrating the Ayreon universe and a booklet containing new photos, lyrics, and notes on the story are also available in the Timeline package.
