SS Carl D. Bradley was an American self-unloading Great Lakes freighter that sank in a Lake Michigan storm on November 18, 1958. Of the 35 crew members, 33 died in the sinking. Twenty-three were from the port town of Rogers City, Michigan, United States. Her sinking was likely caused by structural failure from the brittle steel used in her construction as well as extensive use through her 31 year career.
