Sir John Orde, 1st Baronet (22 December 1751 – 19 February 1824) was the third son of John Orde, of Morpeth, Northumberland, and the brother of Thomas Orde-Powlett, 1st Baron Bolton. Remembered as a professional enemy of Nelson, Orde's quarrel was actually more with Lord St Vincent and he never attacked Nelson personally. Orde joined the Navy in 1766, gained the rank of Rear-Admiral in 1795, Vice-Admiral in 1799 and eventually Admiral of the Red. In 1805, despite being asked to strike his flag, he was made Admiral of the Blue and Admiral of the White in 1810.
