USS Sequoia is a former United States presidential yacht used from Herbert Hoover to Jimmy Carter, who had it sold in 1977. The ship was decommissioned under Roosevelt and lost its "USS" status at that time, but by popular convention is still often used.

The yacht is 104 feet (32 m) long, with a wooden hull, and was designed by John Trumpy Sr., a well-known shipbuilder. It includes a presidential stateroom, guest bedrooms, a galley and dining room, and was at one time retrofitted with an elevator for Franklin D. Roosevelt (Lyndon Johnson had it removed and replaced with a liquor bar).

The ship was designated a National Historic Landmark in 1987.

Following years of neglect and legal battles over ownership, Sequoia is last reported to be in extremely poor condition in Chesapeake Boat Works in Deltaville, Virginia (2017). Her owners estimate that removal of the yacht would require a specialized crane and complete reconstruction of the hull.
