Sergeant Floyd is a historic museum boat, serving as the Sergeant Floyd River Museum & Welcome Center at 1000 Larsen Park Road in Sioux City, Iowa. Built in 1932 as a utility vehicle and towboat, she is one of a small number of surviving vessels built specifically for the United States Army Corps of Engineers in its management of the nation's inland waterways. The boat has been restored and drydocked, and now houses exhibits about the Missouri River and local tourism information. The museum is a facility of the Sioux City Public Museum.
She was declared a National Historic Landmark in 1989.
