SS S.C. Baldwin was a wooden-hulled steam barge built in 1871, that capsized in a storm on August 26, 1908, on Lake Michigan, off Two Rivers, Wisconsin, United States, with the loss of one life.

On August 22, 2016 the remnants of S.C. Baldwin were listed in the National Register of Historic Places as reference number 16000565.

In April 1882 she was sold to David Whitney Jr. of Detroit, Michigan, and her second deck was removed in order to refit her for the lumber trade.

[8][3] In September 1886 S.C. Baldwin went aground in Lake George in the St. Marys River with the freighter R.J. Hackett; both of them were released by the tug Mystic.

On November 5, 1894 S.C. Baldwin collided with the steamer Iron King off Marine City, Michigan, and sank in 35 feet (11 m) of water.

[8] In 1903 S.C. Baldwin was traveling from Green Bay, Wisconsin to Buffalo, New York with a cargo of lumber when she struck an ice pack and sank in Green Bay, about 10 miles (16 km) north of the entrance to the Fox River, near Long Tail Point.

In July, 1904 the Green Stone Company decided to convert S.C. Baldwin to a barge, and removed her machinery in the winter of 1904.

[3] On August 26, 1908 S.C. Baldwin, and scow No.37 were headed south from Sturgeon Bay, Wisconsin with a cargo of stone, in tow of the tug Torrent.

The three vessels encountered a storm as they were passing Kewaunee, Wisconsin, and at around midnight, S.C. Baldwin began taking on water.
