Jack Strap is a minor antagonist of the 1959 James Bond novel Goldfinger and its 1964 film adaptation. He is a mafia boss who was in league with Auric Goldfinger.
He was portrayed by the late Hal Galili.
Jack Strap happens to be one of the crime bosses (alongside Mr. Solo and Jed Midnight) contacted by Goldfinger in his Kentucky home to learn about Goldfinger's plot, and that Strap has provided capsules of nerve gas that can be fatal. At first, Strap gets impatient and demanded for $1 million for delivering the gas, but Goldfinger reveals his plot called Operation Grand Slam, which would involve spreading the gas across the area of Fort Knox that can kill all the guards so that he can send his private task force to raid the fort. Goldfinger then proclaims that he would use the stolen gold bullion to pay the millions of dollars to the crime bosses as promised.
Upon learning this, Strap and the other bosses accept Goldfinger's proposal, but Mr. Solo refuses to be a part and leaves, resulting him to be killed by Oddjob. However, it turns out that Goldfinger actually plans to destroy the gold rather than stealing it so that the value of his gold will increase to become the richest man in the world, and that he has no intention in paying Strap and the other crime bosses. With that in mind, Goldfinger gets Kisch to seal the room and spray the nerve gas, killing Strap and all the other crime bosses.
