Sawyer will be replacing Charlie Gibson on ABC's "World News" beginning in January.
"There is no one like Charlie Gibson and it is an enormous honor to be asked to join the terrific broadcast he and the great team of journalists have built at 'World News,'" Sawyer said in a statement.
"Until then, I'll be getting up early and spending mornings, as always, counting myself so lucky to be with Robin [Roberts], Chris [Cuomo] and Sam [Champion] and the incredibly smart, talented and dedicated team of 'Good Morning America.'"
Gibson has been the anchor of "World News" since May 2006, after replacing Elizabeth Vargas and Bob Woodruff.
