Wickard v. Filburn (1942) was a United States Supreme Court decision which related to the Commerce Clause of the United States Constitution which allows the United States Congress "To regulate Commerce ... among the several States."

During the New Deal, under the Agricultural Adjustment Act, Roscoe Filburn was a farmer who argues that his wheat did not fall under production quotas as the excess never left his farm, being consumed there. The Supreme Court held that even though it was not part of interstate commerce, it affected national markets, thus was part of "Commerce ... among the several States."

The case has recently (as of 2004) been revived in the case of Ashcroft v. Raich about the Controlled Substances Act and medical marijuana. Pending the results of Ashcroft v. Raich, the Supreme Court also has on its docket United States v. Stewart, a case relating to the Federal banning of homemade machine guns.
