In Search of Sunrise 6: Ibiza (also known as ISOS 6) is the sixth album in the In Search of Sunrise series mixed by trance DJ/producer Tiësto, released on 7 September 2007 in the Netherlands and 16 October 2007 in the United States as a double disc album.

A special release party was held at the Heineken Music Hall in Amsterdam on 3 November 2007.

Inspiration to produce this album came from returning to Ibiza after a two-year stint in June 2007.

Tiësto also stated on his website on 13 August 2007, "Most of the tracks are so exclusive that, if I'd still be mixing with records, I wouldn't have been able to get those productions on vinyl!

"[2] On 17 August 2007 on Tiësto's MySpace blog, a thirty-second promotional video was released on YouTube.
