General Gervais Parker (also spelled Gervase; 1695 – 19 June 1750) was a British Army officer. He was the elder surviving son of the Jacobite Colonel John Parker by his first wife Johanna Rouse. His younger brother, Rear-Admiral Christopher Parker, was the father of Admiral of the Fleet Sir Peter Parker, 1st Baronet. The family went into exile in France following Colonel Parker's service at the Battle of the Boyne, but Gervais escaped from his father and joined the English army.
