Waddell is an unincorporated community in Maricopa County, Arizona, United States, northwest of the city of Phoenix. The original Waddell area is located right off Waddell Rd. and between Citrus Rd. and 186th Avenue. It was established sometime in the 1930s when a citrus farmer named Truman began farming the land. The very first citrus tree planted by Truman, on the corner of Waddell Rd. and Cotton Lane, stayed standing as a landmark until February 2009 due to development. Some unincorporated areas west of Surprise, Arizona, may still identify as being part of Waddell. The city of Surprise offered to annex the town but was denied by the HOA. With the expansion of Surprise, use of the name Waddell to describe the location is rapidly falling into disuse. Influence of the name can still be seen in the name of Waddell Road, an arterial street running through Surprise, as well as the New Waddell Dam at Lake Pleasant.
