Mr. O’Brien, the former late-night host, will take over from Jimmy Kimmel, who served as M.C. for the last two Oscar ceremonies, organizers said on Friday.

The 97th annual Oscars will be held on March 2 in Los Angeles. In June, it was reported that Jimmy Kimmel had declined to return to emcee the ceremony.

Conan O’Brien, the Emmy-winning comedian, writer, producer, and former late-night television host, has been selected to host the 97th Academy Awards, the Academy of Motion Picture Arts and Sciences announced on Friday.
