Sir John Orde, 1st Baronet (22 December 1751 – 19 February 1824) was a British Royal Navy officer. The third son of John Orde, of Morpeth, Northumberland, and the brother of Thomas Orde-Powlett, 1st Baron Bolton, he is remembered as a professional enemy of Nelson. Orde's quarrel was actually more with Lord St Vincent and he never attacked Nelson personally. As a vice admiral in 1805 he commanded a squadron of six ships of the line off Cadiz, in the flagship HMS Glory.
