DuPont, Washington - DuPont is a city in Pierce County, Washington, United States. The population was 8,199 at the 2010 census.

Today, DuPont is still a growing community. The elementary school in DuPont (Chloe Clark Elementary), which hosted kindergarten through fifth grade, reached capacity in the 2007-2008 school year. As a result, starting with the 2008-2009 school year, Steilacoom School district realigned all three elementary schools. Chloe Clark Elementary and Cherrydale Primary in Steilacoom now only have students in grades K-3. Saltar's Point Elementary in Steilacoom now serves 4th and 5th grades. Pioneer Middle School relocated from Steilacoom to Dupont in August 2008. The new school received the LEED award for its “Green" Design elements.

DuPont is divided into several "villages", each with their own design style and/or building contractors. Northwest Landing is the most visible due to a sign along the freeway announcing it. Several businesses have opened in the downtown area, but development has slowed in recent years. Hoffman Hill is the largest in size, and houses about 60% of the total population. The Historic Village, a residential area, is the only part of DuPont that is not a modern planned community and is on the registry of historic places. Bell Hill is considered the most expensive area. Dupont has trails and green belts throughout, and is about 95% built out according to the master plan. Sections that remain empty are stalled due to economic conditions, or pre-existing activities that prevent development until completed.

Within the city limits of DuPont, next to city hall, lies Sequalitchew Creek trail which can be accessed by the old narrow gauge railway roadbed which ran from the old Powderworks plant to Puget Sound. The trail leads to Sequalitchew Beach. The creek corridor is used by hundreds of species, including bald eagles, hawks, McKay's bunting, song birds, herons, ducks, owls, frogs, salamanders, snakes, beaver, raccoons, coyotes, deer, and rabbits. The waters off Sequalitchew Beach are inhabited by harbor seal, marbled murrelet and gray whale.
