(1899 - November 23, 1965), was a Chicago mobster of Welsh descent who was the chief political and labor racketeer in the Chicago Outfit during the Prohibition. It has been suggested that the nickname "the Camel" derived from his preference for wearing camel hair coats. However, a more likely explanation is that "the camel" evolved from his other nickname, "the Hump", which came from his last name.

Joining the Chicago Outfit in the mid to late 1920s, Humphreys worked with Al Capone to build relationships with Chicago politicians, businessmen, and labor leaders. Humphreys feuded with Capone over the control of the Outfit until Capone went to prison in 1931 for tax evasion. Humphreys was later indicted for the December 1931 kidnapping of Union president Robert G. Fitche, but escaped conviction.

In 1933, Humphreys helped Al Capone arrange a fake kidnapping. The "victim" of this crime was to be John "Jake the Barber" Factor, a British con artist wanted in his home country for stock swindling. Factor, a Capone friend, was facing extradition proceedings when Humphreys faked his disappearance. In addition, Humphreys framed Capone rival Roger "Terrible" Touhy with the kidnapping charge. Touhy received a 99 year prison sentence.

In 1959, Touhy was finally released from prison. However, a month later Roger Touhy was found murdered. Six months after Touhy's death, Humphreys supposedly bought several shares of an insurance company. Eight months later, Humphreys redeemed these shares for $42,000. An IRS investigation soon determined that these shares had been originally owned by John Factor. The IRS claimed that the $42,000 was a payment from Factor to Humphreys for the fake 1933 kidnapping; they forced Humphreys to declare the money as income and pay taxes.

In 1965, Humphreys was charged for perjury to a federal grand jury. While being arrested, Humphreys pulled a gun on FBI agents, but was disarmed. However, the National Crime Syndicate was reportedly alarmed by this latest example of erratic behavior; within hours of his arrest, Murry Humphreys was found dead of a heart attack. A small wound was discovered on the body near the right ear, raising speculation that Humphreys was killed by an injection of air from a hypodermic needle. This theory was never confirmed.
