An American Political Action Committee (PAC) is an organization formed to raise and spend money to elect or defeat political candidates, influence legislation, or advocate for specific issues.

PACs are a critical component of the U.S. political system, providing a way for individuals, corporations, labor unions, and other interest groups to pool their resources and amplify their impact on the political process. These committees are subject to regulations by the Federal Election Commission (FEC) regarding fundraising and spending, ensuring transparency and accountability in their activities.
