The Citizens' Commission to Investigate the FBI was an activist group operational in the US during the early 1970s. Their only known action was breaking into a two-man Media, Pennsylvania, office of the Federal Bureau of Investigation (FBI) and stealing over 1,000 classified documents. They then mailed these documents anonymously to several US newspapers to expose numerous illegal FBI operations which were infringing on the First Amendment rights of American citizens. Most news outlets initially refused to publish the information, saying it related to ongoing operations and that disclosure might have threatened the lives of agents or informants. However, The Washington Post, after affirming the veracity of the files which the Commission sent them, ran a front-page story on March 24, 1971, at which point other media organizations followed suit.

Media is a borough in and the county seat of Delaware County, Pennsylvania, United States. It is located about 13 miles (21 km) west of Philadelphia. It is part of the Delaware Valley.
