The Network Contagion Research Institute (NCRI) is an American organization dedicated to identifying and predicting the spread of ideologically motivated threats (e.g. hate groups), disinformation, and misinformation across social media platforms and physical spaces.

[3] Examples of NCRI's research include reports on QAnon supporters,[4] militia/boogaloo movements,[3][5] anarcho-socialist networks,[6] antisemitism,[7] racial supremacism, and other topics related to xenophobia.

[12] Other research areas include the study and prevention of sextortion,[13] child sexual abuse,[14] and the negative consequences of DEI programs, such as workplace hostility and racial bias.

[15] Media scholar Jack Bratich has criticized the NCRI for a lack of neutrality, accusing it of being used to target domestic dissenters labelled as threats.

[16] In 2021, the NCRI was criticized by Matthew Lyons of the anti-fascist project Three Way Fight for equating undesirable political views on the left and right, particularly in the wake of the George Floyd protests and for allegedly aligning with state security interests.
