An advocacy organization is a group or association that actively promotes, supports and defends a specific cause, issue or policy. They typically work to influence public opinion, government policies, and/or corporate practices in favor of their stated mission. Advocacy organizations may use various strategies such as lobbying, grassroots mobilization, media campaigns, litigation, and research to achieve their goals. Their primary focus is on advocating for change or reform rather than providing direct services to individuals. Examples of advocacy organizations include civil rights groups, environmental advocates, labor unions, and humanitarian aid agencies among others.
