Hyak was a sternwheel steamboat that operated in British Columbia on the Columbia River from 1892 to 1906. Hyak should not be confused with the Puget Sound propeller-driven steamboat also named Hyak. The name means "swift" or "fast" in the Chinook Jargon.
Hyak was operated on the upper Columbia route from Golden to Windermere Lake. In 1903 Hyak was sold to the Columbia River Lumber Company, which hired Armstrong to manage its steamboat operations.
