Marvin Ammori is an American lawyer, activist, and scholar best known for his work on network neutrality and Internet freedom issues generally. He is a Future Tense Fellow (formerly a Bernard L. Schwartz Fellow) at the New America Foundation and serves on the boards of public interest advocacy groups Demand Progress and Fight for the Future.  He is the author of an e-book entitled "On Internet Freedom," which was released in 2013.
In 2007, while serving as the General Counsel for nonprofit advocacy group Free Press, he brought the Comcast-BitTorrent case, the first network neutrality enforcement action in the United States. Ammori took part in the debate over the controversial copyright bills SOPA and the PROTECT IP Act, arguing that the bills would violate the First Amendment. Partly for his role in opposing SOPA and PIPA, Ammori was recognized on Fast Company's 2012 "100 Most Creative People in Business." Ammori later proposed a holiday called "Internet Freedom Day," to be celebrated on January 18, the anniversary of the SOPA Blackout.
Ammori was a law professor at the University of Nebraska–Lincoln College of Law, where his scholarship focused on First Amendment doctrine. He remains an Affiliate Scholar with Stanford Law School's Center for Internet and Society and an Affiliate Fellow of the Yale Law School Information Society Project. Ammori is a graduate of the University of Michigan and Harvard Law School.
