USS Saratoga, a sloop-of-war, was the third ship of the United States Navy to be named for the Battle of Saratoga of the American Revolutionary War. Her keel was laid down in the summer of 1841 by the Portsmouth Navy Yard. She was launched on 26 July 1842 and commissioned on 4 January 1843 with Commander Josiah Tattnall III in command.

The Battles of Saratoga marked the climax of the Saratoga campaign, giving a decisive victory to the Americans over the British in the American Revolutionary War. British General John Burgoyne led an invasion army of 7,200–8,000 men southward from Canada in the Champlain Valley, hoping to meet a similar British force marching northward from New York City and another British force marching eastward from Lake Ontario; the goal was to take Albany, New York. The southern and western forces never arrived, and Burgoyne was surrounded by American forces in upstate New York 15 miles (24 km) short of his goal. He fought two battles which took place 18 days apart on the same ground 9 miles (14 km) south of Saratoga, New York. He gained a victory in the first battle despite being outnumbered, but lost the second battle after the Americans returned with an even larger force.
