Guardian Mountain is a 5,060 ft (1,540 m) glaciated mountain summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska. The peak is situated in the southern portion of the Juneau Icefield, 15 mi (24 km) northeast of Juneau, and 2.4 mi (4 km) southwest of Slanting Peak which is its nearest higher neighbor. Guardian Mountain is a nunatak surrounded by the Norris Glacier, on land managed by Tongass National Forest. This peak's local name was published in 1960 by the U.S. Geological Survey.

Based on the Köppen climate classification, Guardian Mountain is located in a subarctic climate zone, with long, cold, snowy winters, and cool summers. Weather systems coming off the Gulf of Alaska are forced upwards by the Coast Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The month of July offers the most favorable weather to view or climb Guardian Mountain.
