The Securities Act of 1933, also known as the 1933 Act, the Securities Act, the Truth in Securities Act, the Federal Securities Act, and the '33 Act, was enacted by the United States Congress on May 27, 1933, during the Great Depression and after the stock market crash of 1929. It is an integral part of United States securities regulation. It is legislated pursuant to the Interstate Commerce Clause of the Constitution.

It requires every offer or sale of securities that uses the means and instrumentalities of interstate commerce to be registered with the SEC pursuant to the 1933 Act, unless an exemption from registration exists under the law. The term "means and instrumentalities of interstate commerce" is extremely broad and it is virtually impossible to avoid the operation of the statute by attempting to offer or sell a security without using an "instrumentality" of interstate commerce. Any use of a telephone, for example, or the mails would probably be enough to subject the transaction to the statute.
