Gregory Antone Prince (born 1948) is an American pathology researcher, businessman, author, social critic, and historian of the Latter Day Saint movement.

After spending more than a decade at NIH and Johns Hopkins University, he co-founded Virion Systems, Inc. (VSI), a biotechnology company focused on the prevention and treatment of pediatric infectious diseases.

Building on discoveries that Prince made as a doctoral student, VSI pioneered the prevention of respiratory syncytial virus (RSV) disease in high-risk infants through the use of monoclonal antibody.

In the 2010s, Prince began to call for a better understanding, within the views common among Latter-day Saints, of certain causal relationships between biology and sexual orientation.

[3][4] In recognition of his lifetime achievements, Prince was inducted into the Dixie State College Hall of Fame in 1999, and in 2012 was awarded an Honorary Doctorate of Humanities by the same institution.
