Jeffrey Andrew Weinstock (born January 24, 1970) is an American literature, film, and media scholar who has been teaching in the Department of English Language and Literature at Central Michigan University since 2001. He has authored or edited more than thirty books and a range of articles focusing on the American Gothic tradition, monsters, cult film and television, popular culture, weird fiction, pedagogy, and goth music.

Weinstock is the associate editor in charge of horror for the Los Angeles Review of Books, the founder and president of the Society for the Study of the American Gothic, the founder and general editor of the peer-reviewed journal American Gothic Studies, and the co-founder and past chair of the Modern Language Association’s Gothic Studies Forum. He was the 2019 recipient of the Poe Studies Association's James W. Gargano Award for the best scholarly article on Poe and the 2024 recipient of the Science Fiction Research Association’s Thomas D. Clareson Award for Distinguished Service to the field of speculative literature and media studies. Also in 2024, his monograph, Gothic Things: Dark Enchantment and Anthropocene Anxiety, was short-listed for the International Gothic Association's Allan Lloyd Smith Prize for the scholarly monograph considered to have advanced the field of Gothic studies significantly.

Weinstock graduated from the University of Pennsylvania with a B.A. in English. He then earned an M.A. in American literature and both an MPhil and PhD from the Program in the Human Sciences at The George Washington University. He joined the faculty of the Department of English Language and Literature at Central Michigan University in 2001.

Weinstock's academic work has covered a variety of research areas, but clusters around theorizing the ways in which Gothic texts and practices give shape to culturally specific anxieties and desires.

Of particular interest to Weinstock have been the roles that monsters play in enforcing social norms while also highlighting desires to transgress those same norms. In an early article on freaks and freak shows, "Freaks in Space: ‘Extraterrestrialism’ and ‘Deep-Space Multiculturalism’," Weinstock adapts Edward Said's concept of Orientalism to address the ways in which contemporary racial stereotypes find expression in science fiction film and television through the role of the extraterrestrial.

In the introduction to the Ashgate Encyclopedia of Literary and Cinematic Monsters, the 2014 encyclopedia he edited, he draws upon the work of anthropologist Mary Douglas to discuss monsters as violations of established cultural categories whose transgression of conceptual frameworks creates anxiety. This work won the 2014 Rue Morgue Magazine "Best 2014 Non-Fiction Book" award, as well as the 2014 "Golden Ghoul" award for "Best 2014 Non-Fiction Horror Book" from the Serbian Cult of the Ghoul publication.^{[citation needed]}

In "Invisible Monsters: Vision, Horror, and Contemporary Culture," his contribution to Asa Mittman and Peter Dendle's Ashgate Research Companion to Monsters and the Monstrous, Weinstock proposes that twenty-first century Western culture has decoupled monstrosity from appearance creating concerns that monsters cannot be identified in advance of their attacks. To develop this argument, he focuses on serial killers, terrorists, faceless corporations, viruses, and natural phenomena such as global warming. In "American Monsters," a chapter included in Charles L. Crow's A Companion to the American Gothic, Weinstock addresses the cultural construction of American monsters paying attention to the roles of race and religion in creating monstrous others.

In 2020, Weinstock published The Monster Theory Reader, an edited collection of writings about monsters. This was followed in 2023 by Monstrous Things: Essays on Ghosts, Vampires, and Things That Go Bump in the Night, a collection of previously published articles on monsters. Relatedly, he and Regina Hansen published the co-edited collection of scholarly essays, Giving the Devil His Due: Satan and Cinema, 2021.
