Youngtown is a town in Maricopa County, Arizona, United States.

In 1954, two developers bought 320 acres (1.3 km2) of farmland and built the United States' first planned community dedicated exclusively to retirees.

[9][11][12][13] In 1996, the town, citing its age restrictions, denied extending the stay of a 16-year-old child to live in the community.

In response, Arizona attorney general Grant Woods investigated and determined that the age ordinance was unenforceable.

[14] Youngtown is located on the east bank of the Agua Fria River, just south of US 60.

It is bordered on the west by El Mirage, on the south by Glendale, and on the east by the much larger retirement community of Sun City.

[19] The Peoria Unified School District serves a portion of Youngtown.

Valley Metro Bus route 106 serves the east border of Youngtown on 111th Avenue.
