Armin van Buuren (born December 25, 1976) is a trance music producer and DJ. He was born in Leiden, Netherlands, but grew up in Koudekerk aan den Rijn. He has been voted #1 DJ in the world by DJ Mag's Annual Top 100 DJs of the year 2008. He was also the #1 for 2007.

Armin van Buuren pursued his career as a professional musician despite the promise of a career in law in his native country, the Netherlands, where he completed his law degree in 2004. Armin started working as a DJ in a local night club called Nexus, finished high school in 1995 and went on to university to study law. Meanwhile, he moved his studio equipment from his bedroom to a 'real' studio. The first tracks he produced in his new studio were, among others, tracks like "Touch Me" and "Communication". Van Buuren has been quoted as saying, "Don't be a prisoner of your own style." He has described his musical style as "liberating, euphoric, uplifting, melodic and energetic." He is also known to be an influential Christian trance artist known at clubs and other electronica events.

He hosts a weekly radio show A State of Trance, which mostly consist of progressive and other genres rather than trance. The show completed its 350th episode in May 2008, running for over 7 years.

In October 2002, van Buuren was voted Number 5 in the DJ Magazine 100 top DJs. The following year, he jumped up to the #3 spot, and held 3rd place for the next 3 years. His work left him at the #2 spot, just below Paul van Dyk in the 2006 polls; and in 2007 and 2008 Armin reached Number 1, heading the 2007 DJ Mag Top 100.
