The Gila Bend Mountains are a 35-mile (56 km) long mountain range of the north-central Sonoran Desert southwest of Phoenix, Arizona and in southwest Maricopa County.

The famous Gila Bend of the river changes the west-southwest flow to south-flowing, then back to west-flowing.

Centennial Wash borders the north of the range and has its junction with the Gila River in the Arlington State Wildlife Area.

The highest elevation in the mountains is Woolsey Peak at 3,170 feet (966 m),[1] in the range's center-east.
