Why[a] is an unincorporated rural community in Pima County, Arizona, United States.
It lies near the western border of the Tohono Oʼodham Indian Reservation and due north of Organ Pipe Cactus National Monument in Southern Arizona.
It is approximately 30 miles (48 km) north of the Mexican border where Lukeville, Arizona, and Sonoyta, Sonora, Mexico, border each other, and 10 miles (16 km) south of Ajo, Arizona.
[1] The town derives its name from the fact that two major highways, State Routes 85 and 86, originally intersected in a Y-intersection.
The Arizona Department of Transportation (ADOT) later removed the old Y-intersection for traffic safety reasons and built the two highways in a conventional intersection south of the original intersection.
