"Crystal Ball" is a song performed and composed by English rock band Keane, featured on their second studio album, Under the Iron Sea (2006).

It was recorded at the Helioscentric Studios, East Sussex and at the Magic Shop, New York City.

The demo version included on the bonus DVD of the album would reprise the intro riff before the finale.

The music video for "Crystal Ball" was released by NME on 4 August 2006 and features the American actor Giovanni Ribisi.

He shows off a house to a couple, implying that he is a real estate agent, and working in the office.

After making phone calls and wandering around, the man wakes up in his car in the parking lot of his office.

He begins to argue with him and stops when he sees that the photographs on his desk now show the other man with his family.

At around the time of this single release it was announced that Tom Chaplin had gone into rehab for 'drug and alcohol addiction'.

It is noticeable that the original video does not feature any close up shots of Chaplin, but several of Tim Rice-Oxley and Richard Hughes, though it is unknown whether this is deliberate.

The cover art designed by Sanna Annukka is also found in the inner pages of the Under the Iron Sea DVD.
