Built by the Seattle Shipbuilding Company in 1933, the Nenana is a historic river steamboat currently located in Fairbanks, Alaska. Officially known as SS Nenana, the steamboat primarily carried cargo and passengers on the Yukon and Chena Rivers as a towboat for the Alaska Railroad.

The Nenana is a western rivers style, wooden hulled steam sternwheel riverboat. It is only one of the three steam-powered passenger sternwheelers that is still in existence in the United States, and is also the largest of the lot.

Measuring 237 feet long, the Nenana is now a part of the Alaskaland Historical Park in Fairbanks. It has always been a ship museum since 1967, years after it was decommissioned in 1952. It has also been declared as a National Historic Landmark in 1989.
