SS Chief Wawatam was a coal-fired train ferry and icebreaker that operated in the Straits of Mackinac between 1911–1984. Her home port was St. Ignace, Michigan, and she shuttled back and forth during her entire working life between that port and Mackinaw City, Michigan.

The Chief Wawatam was designed by Great Lakes marine architect Frank E. Kirby. She was launched in Toledo, Ohio, by the Toledo Shipbuilding Company on 26 August 1911, and went into service for the Mackinac Transportation Company on 18 October 1911. The Mackinac Transportation Company was a joint venture of the Duluth, South Shore and Atlantic Railway, the Grand Rapids and Indiana Railroad, and the Michigan Central Railroad, the three railroads that serviced the Straits of Mackinac.

Year-round train ferry service in the Straits of Mackinac was a significant challenge because of the heavy ice buildup experienced by these straits in winter. The Chief Wawatam was designed to break ice floes with her bow propeller, which could both maneuver the boat and suck water out from underneath the ice to enable it to be broken through force of gravity.

The Chief Wawatam was 338 feet in length and had a beam of 62 feet. Her three propellers, two in the stern and one on the bow, were driven by coal-fired triple-expansion steam engines. The Chief is believed to have been the last hand-fired, coal-burning boat in commercial service on the Great Lakes. Other coal-burning vessels that survived longer in revenue service, such as the SS Badger, had automatic stokers.
