Luna Lake is a natural body of water that covers approximately 75 acres (0.30 km2) of land.

It is located about three miles (5 km) southeast of Alpine, Arizona, at the elevation of 7,890 ft (2,400 m), and is the centerpiece of the Luna Lake Wildlife Area.

Luna Lake lies at 7,890 feet (2,400 m) on the Apache-Sitgreaves National Forests, as such the facilities located here are managed by that authority.

Because it is a shallow, nutrient-rich lake, it is subject to water quality problems and excessive weed growth.

The Arizona Game and Fish Department annually harvests weeds to help alleviate some of the water quality problems.
