The "Saturday Night Massacre" was a series of resignations over the dismissal of special prosecutor Archibald Cox that took place in the United States Department of Justice during the Watergate scandal in 1973. The events followed the refusal by Cox to drop a subpoena for the Nixon White House tapes at President Richard Nixon's request.

Archibald Cox Jr. was an American legal scholar who served as U.S. Solicitor General under President John F. Kennedy and as a special prosecutor during the Watergate scandal.
