GMO OMG is a 2013 American pseudoscientific documentary film which takes a negative view towards the use of genetically modified organisms used in the production of food, in the United States. The film focuses on Monsanto, a multinational agrochemical and agricultural biotechnology corporation, and their role in the food industry alongside the effects of GMOs and how they are generated.

Directed by Jeremy Seifert and produced by Elizabeth Kucinich, it was given a limited release in the United States on September 13, 2013, and received negative reviews from critics. GMO OMG follows Seifert's search of answers: how do GMOs affect people and the planet. These and other questions take Seifert on a journey from his family’s table to Haiti, Paris, Norway, and agra-giant Monsanto.
