Barbara Walters plans to make her final appearance on "The View" on May 16.
The final taping will be part of a daylong retirement celebration that will include ABC News naming its New York headquarters after her.
Later that night, ABC will air a two-hour prime-time special on her career.
"This was the right time," Walters told AARP The Magazine. The kinds of interviews I did all these years, nobody wants them anymore. You have three minutes of a morning show. That's different from before. I don't want to do anything forever."
Walters, who is 84, began in television in 1961 and became one of the medium's best-known interviewers.
Walters will remain involved behind the scenes as an executive producer at "The View," the daytime talk show she co-created with Bill Geddie in 1997, now in its 17th season.
ABC said Monday that Walters will be a lifelong member of the ABC News team, and will make special appearances as news warrants.
