Campaign Against Antisemitism (CAA) is a volunteer-led charity committed to combating antisemitism through education and rigorous enforcement of the law. With a strong endorsement from 86% of British Jews who feel represented by CAA, it boasts the largest social media following among similar organizations in the UK and Europe. The charity actively works to expose and penalize instances of antisemitism, providing a vital resource for Jews facing hostility in various environments, including schools, workplaces, and online.

CAA's multifaceted approach includes investigations and landmark litigation against individuals and organizations perpetuating hate, alongside innovative media campaigns that raise public awareness. Through its outreach and education programs, CAA aims to equip future generations and institutions with the tools to resist hate. The organization also engages in public affairs, advocating for legal reforms to close loopholes exploited by extremists. Fundraising efforts are crucial for sustaining CAA's initiatives, ensuring they can continue their essential work in promoting justice and support for affected individuals.
