The BBC has won the TV, radio and online rights to the 2015 and 2017 World Athletics Championships.
The event returns to the BBC after the European Broadcasting Union (EBU) won the pan European rights.
As an EBU bid partner, the BBC will be the sole UK free to air broadcaster in Beijing in 2015 and London two years later - returning after a six-year gap.
"We're delighted the Championships are returning to the BBC," said Barbara Slater, Director BBC Sport.
"The 2017 Championships, taking place at the Olympic Stadium will be a huge moment for UK athletics, helping to deliver the Olympic Legacy, and we're thrilled to be bringing the event to our audiences."
The BBC broadcast the 2009 championships in Berlin but missed out in the bidding for the 2011 and 2013 Championships.
The news follows the announcement on Wednesday that the BBC will continue broadcasting
the Six Nations Championship until 2017
