Georges Valentine, Shipwreck archaeological site in Martin County, Florida.

The Georges Valentine is a shipwreck lying on the seafloor off Martin County, Florida, now submerged beneath the water. The sunken vessel offers insights into ship construction and seafaring techniques from its era.

The iron-hulled barque was built in Wallasey, England, in 1869 by Bowdler Chaffer & Company as Cape Clear, a screw steamboat with auxiliary sail on the Australia–Liverpool passenger run. A Bordeaux firm bought her in 1889, renamed her Georges Valentine and stripped the steam machinery except the boiler, rigging her as a three-masted barkentine. Sold to Genoa's Mortola & Simonetti in 1895 and based at Camogli, she carried lumber from Pensacola to South America until she wrecked off Hutchinson Island on 16 October 1904; the site joined the National Register in 2006.

The wreck lies about 100 yards off Hutchinson Island, near the House of Refuge at Gilbert's Bar, whose keeper Captain William E. Rea took in the seven survivors in October 1904. It became Florida's eleventh Underwater Archaeological Preserve on 16 October 2006, and divers can follow a marked trail with an underwater guide to the scattered iron hull and machinery.

The site lies underwater and is accessible only through authorized archaeological expeditions led by specialists. Visitors typically engage with documented findings and research reports available in archives and museums.

The ship was iron-hulled, not wooden: built in 1869 at Wallasey by Bowdler Chaffer & Company and launched as the Cape Clear, a screw steamer with auxiliary sail on the Australia–Liverpool passenger run. In 1889 a Bordeaux firm renamed her Georges Valentine and stripped out the steam machinery except the boiler, re-rigging her as a three-masted barkentine. She measured 189 feet 7 inches (57.79 m).
