Ronald Louis Ziegler (May 12, 1939 – February 10, 2003) was the 13th White House Press Secretary, serving during President Richard Nixon's administration.

At University of Southern California, he was a member of Trojans for Representative Government with future Watergate scandal participants Dwight L. Chapin, Tim Elbourne, Donald Segretti, Gordon C. Strachan, and Herbert Porter.

Historically, White House press secretaries had been recruited from the ranks of individuals with substantial journalistic experience, such as Stephen Early and Pierre Salinger, raising the question of whether Ziegler was qualified for his position.

Particularly in the period following the resignations of such senior administration officials as Bob Haldeman and John Ehrlichman, Ziegler became one of Nixon's closest aides and confidants.

Ziegler was on the plane that Nixon took to Marine Corps Air Station El Toro, near San Clemente, California, as Gerald Ford was sworn into office.

[citation needed] In 1988, Ziegler became president and chief executive of the National Association of Chain Drug Stores, living in Alexandria, Virginia.

[10] He was described by leading truck stop advocate William Fay as "a significant factor in expanding the travel plaza and truckstop industry's presence in the nation's capital."
