Heather E. Heying (born 1969) is an American evolutionary biologist, former professor, and author, who came to national attention following the Evergreen State College protests in 2017.

[25] On January 29, 2021, Heying appeared on Real Time with Bill Maher along with Weinstein, presenting the "Lab Leak" hypothesis around the origins of SARS-CoV-2.
