George O. Poinar, Jr. (born 1936) is an entomologist and writer. He is known for popularizing the idea of extracting DNA from insects fossilized in amber, an idea which received widespread attention when adapted by Michael Crichton for the book and movie Jurassic Park.

Poinar earned a B.S. and M.S. at Cornell University, and remained there for his doctoral studies, receiving a Ph.D. in biology in 1962. He spent many of his years of research at University of California, Berkeley in the Department of Entomology, Division of Insect Pathology.

There, and during travels around the globe, he performed research on the axenic culture of nematodes, nematode parasites of insects and the fossil records of insects and nematodes in amber.
