Parker

Parker is a city located in Armstrong County, Pennsylvania, United States. It is in the extreme northwestern portion of the county. The population was 695 at the 2020 census. The city was named for Judge John Parker, a lead surveyor of Lawrenceburg and founder/owner of Parker's Landing, the two villages combined to create Parker.

Parker is sometimes referred to as the "Smallest City in the USA". Parker was incorporated as a city on March 1, 1873, by special state legislation in the midst of the northwestern Pennsylvania oil boom. The new municipality was called "Parker" and made up the earlier villages of Parker's Landing (on the Allegheny River) and Lawrenceburg (on the bluff above the river). Residents assumed that Parker would quickly become a major population center, and at the height of the oil boom, the population of Parker grew to over 20,000. The boom quickly went bust, however, and by the 1880s the "city" returned to its historic small village size—a population of approximately 1,000.
