The community began as Maricopa Wells, an oasis of watering holes south of the Gila River first noted in Father Eusebio Kino's 1694 journal.

In the 1850s and 1860s Maricopa Wells was a major stagecoach relay station on the San Antonio and San Diego Mail Line and the Butterfield Overland Mail route, and a haven for emigrants following the southern trail to California's gold fields.

The settlement shifted south and east through incarnations as Maricopaville and Maricopa Junction to reach its present site, becoming a railroad junction when the first Maricopa and Phoenix Railroad train left for Phoenix on July 4, 1887.

Maricopa's Amtrak station, opened in 2001, is the closest Amtrak stop to Phoenix and is served by the Sunset Limited and Texas Eagle trains.
