John Vincent Kenny (April 6, 1893 – June 2, 1975) was mayor of Jersey City from 1949 to 1953.

Kenny put together a commission ticket that broke Hague's 32-year rule.

Although he only served as mayor until 1953, he remained the real power in Jersey City and Hudson County for three decades.

[5][6] His rule was broken in 1971, when he was indicted by the U.S. Attorney's Office for the District of New Jersey, along with the then-mayor Thomas J. Whelan and former City Council president Thomas Flaherty, on charges of conspiracy and extortion in a multimillion-dollar political kickback scheme on city and county contracts; Kenny pled guilty to federal tax evasion in 1972.

[6] Kenny suffered a heart attack and died on June 2, 1975, in Jersey City.
