Scottsdale is a city in the eastern part of Maricopa County, Arizona, United States, part of the Greater Phoenix Area. Named Scottsdale in 1894 after its founder Winfield Scott, a retired U.S. Army chaplain, the city was incorporated in 1951 with a population of 2,000. The 2019 population was estimated at 258,069. Its slogan is "The West's Most Western Town."
Scottsdale, 31 miles long and 11.4 miles wide at its widest point, shares boundaries with many other municipalities and entities. On the west, Scottsdale is bordered by Phoenix, Paradise Valley and unincorporated Maricopa County land. Carefree is along the western boundary, and shares Scottsdale's northern boundary with the Tonto National Forest. To the south Scottsdale is bordered by Tempe. The southern boundary is also occupied by the Salt River Pima-Maricopa Indian Community, which extends along the eastern boundary, which also borders Fountain Hills, the McDowell Mountain Regional Park and more unincorporated Maricopa County land.
The area that includes what became Scottsdale was originally inhabited by the Hohokam, from approximately 300 BC to 1450 AD. This ancient civilization farmed the area and developed a complex network of canals for irrigation that was unsurpassed in pre-Columbian North America. At its peak, the canals stretched over 250 miles. Many remain extant today, some having been renovated and put back into use in the 20th century.
