London's Olympic Stadium will host a three-day athletics meeting to mark one year since the opening ceremony of the 2012 Games.
The London Anniversary Games will be staged from July 26-28 and will showcase many of the British and international stars of last year's Olympics.
Two days will be dedicated to the London leg of the IAAF Diamond League while a third day will focus on showcasing Paralympic athletes, many of whom will have competed in their own World Championships a few days earlier.
“I am delighted that the London Anniversary Games has been confirmed as three days of international athletics this July," said British Olympic Association chairman and IAAF vice president Lord Coe.
"London 2012 was an amazing year for British sport and what a way to celebrate its success by welcoming the world back to London once more to watch the biggest names in athletics.
“It is an important part of the London 2012 legacy that as many people as possible experience world class sport in the world class facilities at Queen Elizabeth Olympic Park and I’m sure the London Anniversary Games will go a long way to inspiring the next generation of track and field fans.”
