Tijs Michiel Verwest, OON ( born 17 January 1969), known as Tiësto (Dutch pronunciation: [cɛsto]), is a Dutch musician, DJ and record producer of electronic dance music. Although he has used many aliases in the past, he is best known for his work as DJ Tiësto.

On his latest productions, however, he has dropped the "DJ" label and is now known simply as "Tiësto", an alias which is a twist of his childhood nickname. In 1997, he founded the label Black Hole Recordings with Arny Bink, where he released the Magik and In Search of Sunrise CD series. Tiësto met producer Dennis Waakop Reijers in 1998, and the two have worked together extensively since then.
