The Lofthus is a Norwegian shipwreck near Boynton Beach, Florida, United States. Built in 1868 in Sunderland, England, the iron-hulled vessel was originally christened Cashmere and rigged as a three masted barque. After a career in the East Indian trade Cashmere was sold to a Norwegian firm, renamed Lofthus, and used in the American trade. It is located three-quarters of a mile north of Boynton Inlet, 175 yards offshore from Manalapan. On January 6, 2004, it was added to the U.S. National Register of Historic Places. It also became the eighth Florida Underwater Archaeological Preserve the same year.
