USS Point Defiance (LSD-31) was a Thomaston-class dock landing ship of the United States Navy. She was named for Point Defiance, a location in Pierce County, Washington, the site of a military reservation established by the U.S. Government in 1866. She was the second ship assigned that name. The construction of the first ship, Casa Grande-class dock landing ship Point Defiance (LSD-23), was canceled on 17 August 1945.
