This will be the third consecutive year that the former talk show host has taken on the role.
A former host returning is not a new phenomenon for the Oscars, but it will be the first time since Billy Crystal's glory days in the 1990s that someone has hosted the ceremony three years in a row.
Conan O'Brien, who once wrote for "Saturday Night Live" and "The Simpsons," has been praised for his efforts at the gala.
The 2027 Oscars will take place on Sunday, March 14.
