Update
is a town in Pima County, Arizona, located northwest of Tucson, with a small portion in Pinal County. According to 2006 estimates, the population of the town is 33,000. Marana was the fourth fastest-growing place among all cities and towns in Arizona of any size from 1990 to 2000.
According to the United States Census Bureau, the town has a total area of 120 square miles (190.5 km²), of which, 119.1 square miles (188.2 km²) of it is land and 0.9 square miles (2.3 km²) of it (1.22%) is water.
The town extends along Interstate 10 from the line between Pinal and Pima County to the Tucson city line, excepting the area around the unincorporated community of Rillito. The city has a history of farming and ranching. The Tucson Mountains and the western half of Saguaro National Park are located to the west. Southern Marana has grown considerably since the early 1990s, with the addition of businesses and housing, much of it due to annexation of existing (and previously unincorporated) nearby neighborhoods (somewhat to the dismay of the city of Tucson and competing neighborhood activists, who coveted these areas for themselves.). Phoenix is approximately one hour north via Interstate 10.
