The Smith Act trials of Communist Party leaders were a series of trials held from 1949 to 1958 in which leaders of the Communist Party of the United States (CPUSA) were accused of violating the Smith Act, a 1940 statute that set penalties for advocating the violent overthrow of the government. The defendants argued that they advocated a peaceful transition to socialism, and that the First Amendment's guarantee of freedom of speech and of association protected their membership in a political party. Appeals from these trials reached the US Supreme Court, which ruled on issues in Dennis v. United States (1951) and Yates v. United States (1957).

The first trial of eleven communist leaders was held in New York in 1949; it was one of the lengthiest trials in United States history.
