Marah gilensis, commonly known as the Gila manroot, is a species of flowering plant in the family Cucurbitaceae, endemic to Arizona and New Mexico in the United States.

This produces fleshy climbing shoots in spring, which grow to a height of 6 ft (1.8 m) or more, and scramble over trees and shrubs, clinging to them with coiled tendrils.

It is present in Arizona where it is found in the northwestern, central and southern parts of the state at altitudes of up to 5,000 feet (1,500 m).
