Keystone City

Keystone City is a fictional city in the DC Comics' version of the United States. Specifically, it is the home of both the original Flash, Jay Garrick, and the third Flash, Wally West. Keystone City first appeared in the 1940s in the original Flash series. Within the comics, Keystone has been described as being "the blue collar capital of the United States" and a center of industry.

It is the birthplace of Officer Owens and the hometown of Jenna Duffy, a former henchman for the Ventriloquist.

The techno-criminal known as Mark Mardon was known to have several labs within Keystone.
