DJ Tiesto, twice voted the world's top DJ by the trade press, will become the first entertainer of his kind to perform at the opening ceremony in the 108-year history of the Games.
"The opportunity to perform my music for billions of people around the globe will be the greatest highlight of my life," Dutchman Tiesto said in a statement on Monday.
"I am honoured to be part of the biggest sports event in the world."
Tiesto will perform a 90-minute live set in the Olympic Stadium during the parade of athletes.
"While it is path-breaking, it is also natural that a modern artist like Tiesto will contribute to the celebration we are planning on our opening night," Games chief Gianna Angelopoulos said.
Few other details are known about the opening ceremony, but organisers have promised it will be spectacular.
