Constitution Dock is a rock-walled marina situated on Sullivans Cove in the Port of Hobart, Tasmania, adjacent to Victoria Dock, Salamanca Place, and Battery Point.

Managed by TasPorts, it accommodates a portion of Hobart's fishing fleet along with private yachts and recreational vessels. A bridge controls entry to the dock, remaining closed to allow pedestrian access around its perimeter when not in use.

The dock is best known as the finishing line for the annual Sydney to Hobart Yacht Race, which departs Sydney on Boxing Day and sees finishers arrive to crowds gathered around the waterfront through New Year's Eve.

Beyond race season, the area draws visitors year-round to its seafood stalls, waterfront restaurants, and proximity to the historic Salamanca Place precinct.
