United States v. Eichman, 496 U.S. 310 (1990), was a United States Supreme Court case that invalidated a federal law against flag desecration as a violation of free speech under the First Amendment. It was argued together with the case United States v. Haggerty. It built on the opinion handed down in the Court's decision the prior year in Texas v. Johnson (1989), which invalidated on First Amendment grounds a Texas state statute banning flag burning.
