Mount Bradley is a 3,337-foot (1,017 m) elevation mountain summit located on Douglas Island in the Alexander Archipelago, in the U.S. state of Alaska. It is the third-highest peak on the island, and is situated 4 mi (6 km) south of Juneau, on land managed by Tongass National Forest. Although modest in elevation, relief is significant since the peak rises up from tidewater of Gastineau Channel in approximately two miles. Its nearest higher neighbor is Mount Ben Stewart, 5.6 mi (9 km) to the northwest.
