Tortolita was a census-designated place (CDP) in Pima County, Arizona, United States. The population was 3,740 at the 2000 census. Tortolita was situated between the growing incorporated towns of Oro Valley and Marana with most of the area previously part of the CDP having been annexed by the two towns during the 2000s. The remaining parts of the CDP that have not been annexed continue to be unincorporated portions of Pima County.

In 1997, the residents of Tortolita voted to incorporate as the Town of Tortolita. However, the 1997 law passed by the Arizona legislature that allowed cities and towns within six miles of other incorporated areas to incorporate without those neighboring cities' consent was overturned on constitutional grounds, and the incorporation was deemed invalid.
