The Domestic Violence Offender Gun Ban, often called the "Lautenberg Amendment", is an amendment to the Omnibus Consolidated Appropriations Act of 1997, enacted by the 104th United States Congress in 1996, which bans access to firearms for life by people convicted of crimes of domestic violence. The act is often referred to as "the Lautenberg Amendment" after its sponsor, Senator Frank Lautenberg. Lautenberg proposed the amendment after a decision from the United States Court of Appeals for the Ninth Circuit, involving underenforcement of domestic violence laws brought under the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. President Bill Clinton signed the law as part of the Omnibus Appropriations Act of 1997.

The 104th United States Congress was a meeting of the legislative branch of the United States federal government, composed of the United States Senate and the United States House of Representatives. It met in Washington, D.C. from January 3, 1995, to January 3, 1997, during the third and fourth years of Bill Clinton's presidency. Apportionment of seats in the House of Representatives was based on the 1990 United States census.
