The Comstock Act of 1873 is a series of current provisions in federal law that generally criminalize the involvement of the United States Postal Service, its officers, or a common carrier in conveying obscene matter, crime-inciting matter, or certain abortion-related matter. The Comstock Act is largely codified across title 18 of the United States Code and was enacted beginning in 1872 with the attachment of a rider to the Post Office Consolidation Act of 1872. Amended multiple times since initial enactment, most recently in 1996, the Act is nonetheless often associated with U.S. Postal Inspector and anti-vice activist Anthony Comstock.
The law was applied broadly for much of its history, before the scope of enforcement narrowed after various court rulings, and modern enforcement is primarily focused on prosecuting child pornography (with the most recent conviction under the Act being made in 2021).
