The Anti-Defamation League (ADL) is a Jewish-identified public advocacy group, started in 1913.

The ADL's mandate is to fight anti-semitism and bigotry in general. As such, the ADL has moved over its history from a focus mainly on countering anti-semitism to a broader mission and prides itself as a leading U.S. (and international) watchdog on issues of anti-semitism, bigotry, racism, extremism, countering terrorism, the deterrence (and definition) of hate crimes, Israel-U.S. relations, religious liberty, and educational outreach efforts related to its mission(s).

Their website appears at and provides further background on actions, programs and positions from the perspective of the ADL itself.
