Giacomo "Jake" Amari (died 1997) was the powerful underboss and later acting boss of the DeCavalcante crime family.
According to the testimony provided by Vincent "Vinny Ocean" Palermo, the later acting boss of the DeCavalcante crime family, Amari was a prominent and ruthless captain before being promoted to the acting underboss after the imprisonment of longtime family boss, Giovanni "John the Eagle" Riggi, who had been put on trial for racketeering and extortion charges after developing a great influence inside most of the unions in New Jersey together with Amari. Amari was reportedly a powerful labor racketeer of Newark, New Jersey during the 1980s, and was almost charged with Riggi in extorting the unions into ripping of their welfare and pension funds in the early 1990s.

After reputed captain John "Johnny Boy" D'Amato stepped up as acting boss for Riggi in 1991, Amari developed a great partnership with reputed consigliere Stefano "Steve the Truck Driver" Vitabile, who was also one of the most powerful figures in the DeCavalcante crime family at the time. After longtime official underboss Louis LaRasso disappeared in the summer of 1991, Amari was reportedly promoted to LaRasso's position and fully in charge of all labor and construction racketeering operations, as well as AMI Construction, from Elizabeth, New Jersey.
