The USS Edisto (AGB-2) was a Wind-class icebreaker in the service of the United States Navy and was later transferred to the United States Coast Guard as USCGC Edisto (WAGB-284). She was named after Edisto Island, South Carolina. The island is named after the Native American Edisto Band who inhabited the island and the surrounding area. Currently (2011) there is a namesake cutter USCGC Edisto (WPB-1313). The newer Edisto is a 110-foot Island-class patrol boat and is stationed at San Diego, California.

Edisto was one of the icebreakers designed by Lieutenant commander Edward Thiele and Gibbs & Cox of New York, who modeled them after plans for European icebreakers he obtained before the start of World War II. She was the last of seven completed ships of the Wind-class of icebreakers operated by the United States Coast Guard. Her keel was laid on May 15, 1945 at Western Pipe and Steel Company shipyards in San Pedro, California, she was launched on December 28, 1946, and commissioned on March 20, 1947.

Her outer hull plating was constructed with 1-5/8 inch thick high tensile steel. Edisto had a double bottom above the waterline with the two "skins" being approximately 15 inches apart, insulated with cork. Framing was closely spaced and the entire hull girder was designed for great strength. Edisto's bow had the characteristic sloping forefoot that enabled her to ride up on heavy ice and break it with the weight of the vessel. Edisto's stern was similarly shaped to facilitate breaking ice while backing down. The sides of the icebreaker were rounded, with marked tumble home, that enabled the ship to break free from ice by heeling from side to side. Such heeling was accomplished by shifting water rapidly from wing tanks on one side of the ship to the other. A total of 220 tons of water could be shifted from one side to the other in as little as 90 seconds, which induced a list of 10 degrees. Ballast could also be shifted rapidly between fore and aft tanks to change the trim of the ship. Diesel electric machinery was chosen for its controlability and resistance to damage.
