Located at the opening of the Totten Inlet, the area lies at the northern end of a peninsula known locally as the "Steamboat Peninsula".

Founded in 1909, Steamboat Island was named by local settlers who thought the island resembled a steamboat.

The population is mostly Caucasian and largely made of two person households.

[2] The island is about 400 ft (120 m) due west from Hope Island Marine State Park, which is accessible only by boat.
