The New England regional office of the American Jewish Committee (AJC), a global Jewish advocacy organization serving Massachusetts and surrounding states in New England. It connects the New England community to AJC's global advocacy network of over 30 offices worldwide, focusing on combating antisemitism, advancing the security of Israel and the Jewish people, promoting human rights, democratic values, and intergroup understanding. The office runs leadership programs such as Leaders for Tomorrow (for young professionals), high school initiatives, and events like the annual Diplomats Seder and Co-Existence Awards. It frequently collaborates with JCRC of Greater Boston, ADL New England, and Combined Jewish Philanthropies (CJP). In 2024-2025, it published a report documenting alleged anti-Israel bias and antisemitism within the Massachusetts Teachers Association (MTA), prompting criticism from MTA leadership and related educators' groups.
