Circle City is an unincorporated community and census-designated place (CDP) in Maricopa County, Arizona, United States, located 17 miles (27 km) northwest of Surprise on U.S. Route 60.

[3] The development was built in the late 1950s by The Workmen's Circle, a Jewish fraternal and mutual aid society with roots in the socialist movement of the early 20th century.

The group created the town as a retirement community for its aging members, but also welcomed anyone over the age of fifty to live in the community.

[4] The community welcomed people from all races and religions that were interested a decade before the Fair Housing Act was passed.

[5][6] Ben Schleifer, himself a Jewish immigrant and who created the nearby retirement community of Youngstown, was tasked with designing the community.
