The steamboat Hassalo operated from 1880 to 1898 on the Columbia River and Puget Sound. Hassalo became famous for running the Cascades of the Columbia on May 26, 1888 at a speed approaching 60 miles (97 km) an hour. This vessel should not be confused with other steamboats with the same or a similar name, including Hassalo (1899) and Hassaloe (1857).
