Hugh Joseph Addonizio (January 31, 1914 – February 2, 1981) was an American Democratic Party politician who was sentenced to prison for corruption.

He ran on a reform platform, defeating what he characterized as the corrupt political machine of Leo P. Carlin, who had been mayor since 1953.

[3] In July 1970, the former mayor and four other defendants were found guilty by a federal jury on 64 counts each, one of conspiracy and 63 of extortion.

[4] In September 1970, Addonizio was sentenced to ten years in federal prison and fined $25,000 by U.S. District Court Judge George H. Barlow for his role in a plot that involved the extortion of $1.5 million in kickbacks, a crime that the judge said "tore at the very heart of our civilized society and our form of representative government".

[7] Addonizio died of cardiac arrest in 1981 and was interred in Gate of Heaven Cemetery in East Hanover.
