The Racketeer Influenced and Corrupt Organizations (RICO) Act is a United States federal law that provides for extended criminal penalties and a civil cause of action for acts performed as part of an ongoing criminal organization.

RICO was enacted by Title IX of the Organized Crime Control Act of 1970 (Pub. L. 91–452, 84 Stat. 922, enacted October 15, 1970), and is codified at 18 U.S.C. ch. 96 as 18 U.S.C. §§ 1961–1968.

This article primarily covers the federal criminal statute, but since 1972, 33 U.S. states and territories have adopted state RICO laws, which although similar, cover additional state crimes and may differ from the federal law and each other in several respects.

G. Robert Blakey, an adviser to the United States Senate Government Operations Committee, drafted the law under the close supervision of Senator John L. McClellan, the Chairman of the Criminal Law and Procedures Subcommittee of the Senate Judiciary Committee. ^{[citation needed]}

It was signed into law by U.S. President Richard Nixon. Prosecutors in the 1970s used it to prosecute the Mafia as well as others who were actively engaged in organized crime. In later years, prosecutors have applied the law more broadly.

Under RICO, a person who has committed "at least two acts of racketeering activity" drawn from a list of 35 crimes (27 federal crimes and eight state crimes) within a 10-year period can be charged with racketeering if such acts are related in one of four specified ways to an enterprise.

Those found guilty of racketeering can be fined up to $25,000 and sentenced to 20 years in prison per racketeering count.

In addition, the racketeer must forfeit all ill-gotten gains and interest in any business gained through a pattern of racketeering activity.
