The SS Wisconsin was a steamboat that sank in Lake Michigan off the coast Kenosha, Wisconsin, United States. In 2009 the shipwreck site was added to the National Register of Historic Places. The Wisconsin was built at the Dry Dock Complex in 1881. During World War One, she served as a convalescent hospital ship named the General Robert M. O'Reilly after Robert Maitland O'Reilly, a former Surgeon General of the United States Army. In addition to Wisconsin and General Robert M. O'Reilly, the vessel was also named the Naomi, the E. G. Crosby and Pilgrim. The Wisconsin foundered in October of 1929 after a leak occurred during a violent storm. The wreckage site is a popular location for historians, archaeologists and divers. It lies in 90 to 130 feet (27 to 40 m) of water, 6.5 miles (10.5 km) south-southeast of Kenosha.
