George W. Parshall (September 19, 1929 – July 28, 2019) was an American organometallic chemist who made notable contributions to homogeneous catalysis.

In 1954, he joined Central Research Department at du Pont Experimental Station, where he rose to Director of Chemical Sciences.

Parshall was a senior manager at du Pont during an era of rapid development and commercialization of organometallic chemistry and homogeneous catalysis.

When Parshall retired from DuPont in 1992, he joined the effort to destroy chemical weapon stockpiles in the United States and across the world.

As a member of the National Research Council’s “Stockpile Committee,” he has played a role in advising the U.S. Army in its ongoing effort to safely destroy chemical weapons.
