Joseph Charles Dippolito (December 28, 1914 – January 14, 1974), also well known as Joe Dip, was an Italian American Mafia member in the Los Angeles crime family.

Eventually, the family made large profits selling diamonds bought during the Great Depression at bargain prices from New York, in Ontario, and Los Angeles, California.

Joe Dippolito and his father Charlie, and other family members, soon started and owned several successful businesses on Fourth Street, including a liquor and market store, a hotel, and extensive wine vineyards in what is now Rancho Cucamonga.

In September 1949, Fratianno was ordered by Jack Dragna to set up and kill Mickey Cohen loyalist Frank Niccoli, who was free on bail.

Leaving the front door part way open, in a friendly voice, Jimmy asked Niccoli, "Have you ever met Joe Dip?"

Afterwards, Fratianno said Dippolito took Niccoli's body, and buried it with a sack of lime in his large wine grape vineyard in what is now Rancho Cucamonga, California.

[2] In 1952, Dippolito became a made man in the Los Angeles crime family, serving under L.A. mob boss Jack Dragna.

On January 31, 1969, Joe Dippolito was indicted in a Los Angeles court on three counts of perjury for false statements he made during a liquor license inquiry on May 16, 1968.

Joe Dip was released from prison after San Bernardino Mayor Al C. Ballard, Police Chief Louis J. Fortuna, and California Superior Court Judge Joseph A. Katz vouched for Dippolito in glowing letters written in 1969 to a probation officer.
