Guam Highway 11 (GH-11) is one of the primary automobile highways in the United States territory of Guam.

This spur route from GH-1 runs westward along Cabras Island, a narrow peninsula which forms the northern edge of Apra Harbor.

This area houses Guam's commercial port facilities, making GH-11 an important transport route.

The road's designation ends at the control gate to the access road leading out to the man-made Glass Breakwater.

[1] The entire highway is in Piti, Guam.
