Paradise Valley is a town in Maricopa County, Arizona, USA. The population was 13,664 at the 2000 census. Despite the town's relatively small area and population compared to other cities in the Phoenix metropolitan area, Paradise Valley is home to twelve resorts, making it one of Arizona's premiere tourist destinations. It has prime real estate, with a median resale value at $1.2 million, with many exceeding $5 million and some over $15 million.

It should not be confused with the neighborhood in northeast Phoenix of the same name. For instance, Paradise Valley Community College, Paradise Valley High School, Paradise Valley Hospital, Paradise Valley Mall, and Paradise Valley Golf Course are all located several miles to the north, in Phoenix - a considerable distance from the town that actually bears their name.

Paradise Valley is often considered to be an extension of Scottsdale, another area with a wealthy reputation. Paradise Valley residents attend schools in the Scottsdale Unified School District. There is a Paradise Valley Unified School District, and it is one of the largest in the state, though like many other institutions with Paradise Valley's name, it operates in Phoenix.
