Hotham Inlet is an arm of Kotzebue Sound on the northwestern coast of the U.S. state of Alaska. It is 50 miles (80 km) long and 5–20 miles (8–32 km) wide. The inlet is the outlet of the Kobuk and Selawik Rivers and it is bounded on the southwest by the Baldwin Peninsula. This inlet was named in 1826 by Royal Navy Captain Frederick William Beechey after Sir Henry Hotham, one of the lords of the British Admiralty.
