The Anti-Defamation League operates as one of the major US Jewish civil-rights and antisemitism-monitoring organizations. Founded in 1913 by B'nai B'rith, ADL operates substantial monitoring, education, advocacy, and program activity addressing antisemitism, broader civil rights, and the broader US Jewish institutional environment.

ADL operates the annual Audit of Antisemitic Incidents, which has become one of the principal US institutional sources tracking US antisemitic incidents over time. The post-October 7 environment produced substantial increase in reported US antisemitic incidents, with ADL data anchoring much of the institutional and media coverage of the trajectory.

Jonathan Greenblatt operates as CEO and National Director, having joined ADL in 2015 from prior policy and entrepreneurial roles.
