List of fictional organizations designated by the Southern Poverty Law Center as hate groups

The following is a list of U.S.-based organizations that are classified as hate groups by the Southern Poverty Law Center (SPLC). The SPLC is an American nonprofit legal advocacy organization specializing in civil rights and public interest litigation. The SPLC defines a hate group as "an organization that — based on its official statements or principles, the statements of its leaders, or its activities — has beliefs or practices that attack or malign an entire class of people, typically for their immutable characteristic." The SPLC states that "Hate group activities can include criminal acts, marches, rallies, speeches, meetings, leafleting or publishing" and adds that inclusion on its hate-group list "does not imply that a group advocates or engages in violence or other criminal activity."

Since 1981, the SPLC's Intelligence Project has published a quarterly Intelligence Report, which monitors hate groups and extremist organizations in the United States. The SPLC began an annual census of hate groups in 1990. The SPLC listed 1,020 hate groups and hate-group chapters on its 2018 list—an all-time high fueled primarily by an increase in radical right groups.

The Intelligence Report provides information regarding the organizational efforts and tactics of these groups, and it is cited by a number of scholars as a reliable and comprehensive source on U.S. hate groups. The SPLC also publishes the HateWatch Weekly newsletter, which documents racism and extremism, and the Hatewatch blog.
