Carefree is a town in Maricopa County, Arizona, United States. According to 2006 Census Bureau estimates, the population of the town is 3,799.
Characterised as an upscale residential area, Carefree was conceived in the mid-1950s by business partners K.T. Palmer and Tom Darlington as a master-planned community. Land sales commenced in 1955 and homebuilding followed shortly thereafter in 1958. Typical of Carefree's character are its street names—Tranquil Trail, Easy Street, Ho-and-Hum Roads and Long Rifle, Stagecoach and Bloody Basin—which reflect both its quiet, casual air as well as its Western heritage. The motto of Carefree is "Home of Cowboys and Caviar, Where the Old West Meets the New."
The Carefree sundial, designed by architect Joe Wong and solar engineer John I. Yellott, was erected in the Sundial Circle plaza in 1959 and is the "third largest sundial in the Western Hemisphere". The sundial, which points to the North Star, is made from a steel frame and covered in anodized copper. It measures 90 feet (27 m) in diameter. The metal gnomon, the shadow-casting portion of the dial, stands 35 feet (11 m) above the plaza and extends 72 feet (22 m).
