David J. Cannon (August 6, 1933 – July 26, 2011) was an American attorney who served as Milwaukee County District Attorney from 1968 to 1969 and as United States Attorney for the Eastern District of Wisconsin from 1969 to 1973. Cannon was the last Republican to serve as Milwaukee County District Attorney.
Cannon was born in Milwaukee and attended Marquette University High School. He graduated from Marquette University in 1955 before serving in the United States Army's security agency. In 1960, Cannon received his law degree from Marquette University Law School and entered private practice. He gained notoriety for successfully challenging the authority of Wisconsin district attorneys, and Milwaukee County's corporation counsel, to issue arrest warrants in child support cases. In 1966, he was hired as a Milwaukee County prosecutor by District Attorney Hugh O'Connell. When O'Connell was elected to the Milwaukee County Circuit Court in April 1968, Republican Governor Warren Knowles appointed Cannon to succeed him.
As district attorney, Cannon sought to modernize the office's technology and to redirect its resources against white-collar crime. He prosecuted John Oraa Tucker, a Milwaukee man accused of fatally shooting a police officer during the city's 1967 civil unrest; although Tucker was convicted of several related felonies, he was acquitted of homicide. Additionally, Cannon faced an uphill election battle in the fall of 1968, facing Democrat E. Michael McCann, a former assistant district attorney. In the November general election, McCann defeated Cannon with a margin of approximately 12,000 votes.
