Martin Oliver "Mo" Waldron (February 2, 1925 – May 27, 1981) was an American newspaper reporter. His 1963 series of articles in the St. Petersburg Times exposed the state's "reckless, unchecked spending" on the construction of the Sunshine State Parkway, and was recognized with the 1964 Pulitzer Prize for Public Service. At his death he was the bureau chief for The New York Times in Trenton, New Jersey, the state capital.
