Keller, who will have been with the paper 20 years next year replaces Joseph Lelyveld, who took over as executive editor on an interim basis last month following the abrupt resignation of Raines and his deputy Gerald Boyd.
Blair quit on May 1 after he was exposed for filing stories from his Brooklyn apartment while pretending to be away on assignments, and plagiarising the work of other journalists. As well as Raines and Boyd, the magazine lost one of its top reporters Rick Bragg, who quit over the use of unaccredited freelance journalists.
Keller, 54, took on his senior writer role at the Times in 2001 after serving as managing editor from 1997-2001, following a two-year stint as foreign editor and three years as chief of the Times bureau in Johannesberg from 1992-1995.
He joined the magazine in 1984 as a domestic correspondent in Washington and worked as its Times Russian correspondent in Moscow from 1986-1991, and in 1989 won a Pulitzer Prize for his coverage of the Soviet Union.
Before joining the Times, Keller was a reporter for the Dallas Times Herald, The Congressional Quarterly Weekly Report and The Oregonian in Portland.
Interim editor Lelyveld is a former executive editor of the Times of seven years. During his tenure, the Times won 12 Pulitzer Prizes, introduced colour to its pages, added new sections and expanded its national circulation.
