General Charles O'Hara (1740 – 25 February 1802) was a British Army officer who served in the Seven Years' War, the American War of Independence, and the French Revolutionary War and later served as governor of Gibraltar. He served with distinction during the American War of Independence, commanding a brigade of Foot Guards as part of the army of Charles Cornwallis and was wounded during the Battle of Guilford Courthouse. He offered the British surrender during the siege of Yorktown on behalf of his superior Charles Cornwallis and is depicted in the eponymous painting by John Trumbull. During his career O'Hara personally surrendered to both George Washington and Napoleon Bonaparte.

O'Hara's Battery and O'Hara's Tower in Gibraltar were named after him.
