Tortilla Flat is a small unincorporated community in far eastern Maricopa County, Arizona, United States. It is located in the central part of the state, northeast of Apache Junction. It is the last surviving stagecoach stop along the Apache Trail. According to the Gross Management Department of Arizona's main U.S. Post Office in Phoenix, Tortilla Flat is presumed to be Arizona's smallest official "community" having a U.S. Post Office and voter's precinct. The town has a population of 6. Tortilla Flat can be reached by vehicles on State Route 88, via Apache Junction.
Originally a camping ground for the prospectors who searched for gold in the Superstition Mountains in the mid-to-late 19th century, Tortilla Flat was later a freight camp for the construction of Theodore Roosevelt Dam. From this time (1904) on, Tortilla Flat has had a small (<100 people) but continuous population. A flood in 1942 badly damaged the town, resulting in many residents moving away. Today Tortilla Flat is owned and operated by Alvin Ross, a farmer from Indiana who purchased the town in 1998. The town is made up primarily of a small store and restaurant, which were constructed in the late 1980s after a fire consumed the existing store and restaurant on the same site. Several hiking trails into the Superstition Mountains begin near Tortilla Flat.
