If Then Else (stylized if_then_else) is the sixth studio album by the Dutch rock band The Gathering.

The album was engineered by Zlaya Hadzich and Dick Kemper, mixed and mastered on Pro Tools by Attie Bauw at Bauwhaus Studio, Amsterdam, in April 2000.

Its title combines two frequently used computer programming notations: "Colorado Incident" is about a real-life experience of having to cancel a gig in Colorado because of overbooking, exhaustion and the band members' illnesses.

An excerpt of Lewis Carroll's Alice in Wonderland, narrated by Willie Rushton, is heard between "Analog Park" and "Herbal Movement".

All lyrics are written by Anneke van Giersbergen, except when noted; all music is composed by The GatheringThe Gathering
