Heterodox Academy (HxA) is a nonprofit advocacy group of academics working to counteract what they see as a lack of viewpoint diversity on college campuses.

The organization was founded in 2015 by Jonathan Haidt, Nicholas Quinn Rosenkranz, and Chris Martin, who each cited a lack of politically conservative viewpoints in their academic disciplines.

[4] Membership was initially open to tenured and pre-tenure professors, but has been expanded to a range of other faculty ranks (including career/full-time as well as adjunct/part-time), and even non-faculty positions such as graduate students and postdoctorals.

[16] In June 2018, Heterodox Academy held an inaugural Open Mind Conference in New York City, featuring several academic guests recently involved in campus free speech issues, like Robert Zimmer, Lucía Martínez Valdivia, Allison Stanger, Alice Dreger, and Heather Heying.

[20] According to Vox's Zack Beauchamp, Heterodox Academy advances conservative viewpoints on college campuses by ignoring the data and arguing that such views are suppressed by left-wing bias or political correctness.
