Stephens Passage is a channel in the Alexander Archipelago in the southeastern region of the U.S. state of Alaska. It runs between Admiralty Island to the west and the Alaska mainland and Douglas Island to the east, and is about 170 km (105 mi) long. Juneau, the capital of Alaska, is near the north end, on Gastineau Channel.
Stephens Passage was named in 1794 by George Vancouver, probably for Sir Philip Stephens. It was first charted the same year by Joseph Whidbey, master of the HMS Discovery during Vancouver's 1791-95 expedition.
