The Electronic Privacy Information Center (EPIC) is a think tank concerned with the impact of technology on privacy and free speech. The organization was founded in 1994 by the Fund for Constitutional Government and the Computer Professionals for Social Responsibility.  EPIC conducts research, files lawsuits against private corporations and government bodies, sends members to testify before Congress, and funds smaller ally organizations.
Though EPIC’s goals are the maintenance of non-partisan civil liberties against private and government incursions, many of its donors are left-of-center nonprofits, and it has partnered with the social-liberal American Civil Liberties Union (ACLU) in litigation against internet pornography regulations and against national-security legislation.
The Electronic Privacy Information Center engages in research, lawsuits, and testimony to forward its goals.
EPIC publishes guides for public consumption on privacy issues. For instance, EPIC created a summary of privacy issues related to the 2020 Federal Census, as well as the privacy risks of cloud computing. 
EPIC has been involved in numerous high-profile lawsuits. 
In the early 1990s, EPIC joined the American Civil Liberties Union (ACLU) in ACLU vs. Mukasey to challenge the Child Online Protection Act, which required all online distributors of pornography to restrict access to minors. 
EPIC has launched two lawsuits with the ACLU against the federal government to demand the public disclosure of information gathered by the PATRIOT Act in accordance with the Freedom of Information Act (FOIA). 
Most of EPIC’s independent lawsuits concern forcing the federal government to release information it collected during investigation efforts which arguably violated the Fourth Amendment. 2004’s EPIC v. DHS demanded that the Department of Homeland Security release records collected on airline passengers. 2006’s EPIC v. DOJ demanded the Department of Justice release National Security Agency data collected while monitoring private phone calls and emails for terrorist activities. 
The Public Voice
The Electronic Privacy Information Center founded The Public Voice in 1996 with funding from the Ford Foundation and Open Society Foundations, two of the largest nonprofit funders of left-of-center causes in America.
The Public Voice is a coalition of nonprofit think tanks and activist groups with similar goals to EPIC. The coalition members have signed declarations for universal AI guidelines and a global moratorium on the use of facial recognition technology for government surveillance systems.  The member organizations are:
- Communication Rights in the Information Society
- Free Press
- Association for Progressive Communications
- European Digital Rights
- Statewatch Bulletin
- GILC Alert
- Transitions Online
- UNESCO Observatory on the Information Society
The Electronic Privacy Information Center receives much of its funding from nonprofit organizations associated with left-of-center causes. It receives no funding nor takes meetings with tech companies. 
EPIC received numerous grants of undisclosed amounts from many other left-of-center organizations, including the Arca Foundation, the John and Mary R. Markle Foundation, and the Rockefeller Family Fund.
