Joseph Saville Cony (1834 – February 10, 1867) was an officer in the United States Navy who served during the American Civil War.
First attached to USS Western World, he commanded several successful small-boat expeditions along the Carolina coast.
On August 22, 1863, while executive officer of USS Shokokon, he commanded a boat expedition of six men which surprised a much larger enemy encampment at New Topsail Inlet, near Wilmington, North Carolina.
This small force captured ten men, one 12-pounder howitzer, eighteen horses, and destroyed the blockade running schooner Alexander Cooper and extensive salt works.
In April 1864, while attached to USS Britannia, he received the thanks of Major General Peck for his cooperation with the landing expedition at Bogue Inlet.
