Carl Milton Bernstein (born February 14, 1944) is an American investigative journalist and author. While a young reporter for The Washington Post in 1972, Bernstein was teamed up with Bob Woodward, and the two did much of the original news reporting on the Watergate scandal. These scandals led to numerous government investigations and the eventual resignation of President Richard Nixon. The work of Woodward and Bernstein was called "maybe the single greatest reporting effort of all time" by longtime journalism figure Gene Roberts.

Bernstein's career since Watergate has continued to focus on the theme of the use and abuse of power via books and magazine articles. He has also done reporting for television and opinion commentary. He is the author or co-author of seven books: All the President's Men, The Final Days, and The Secret Man, with Bob Woodward; His Holiness: John Paul II and the History of Our Time, with Marco Politi; Loyalties; A Woman in Charge: The Life of Hillary Rodham Clinton; and Chasing History, a memoir of his early years in journalism. Additionally, he is a regular political commentator on CNN.
