Vice-Admiral Sir John Tremayne Rodd, KCB (c. 1769 – 4 October 1838) was an officer of the Royal Navy noted for his services during the Napoleonic Wars.

[7] In 1806, Rodd was working in conjunction with Captain Lord Cochrane in HMS Pallas and on 15 July Indefatigable was the launch point for a fleet of small boats that attacked a French convoy in the Gironde.

The same month, Indefatigable was heavily engaged at the Battle of Basque Roads, in which the French fleet in Brest was driven onto shoals by fireships launched by Cochrane who then attacked.

Cochrane was inadequately supported by Admiral Lord Gambier and as a result only five French ships were destroyed instead of the entire fleet.

[6] In 1809, Rodd married Jane, only daughter of Major James Rennell, a geographer, historian, and pioneer of oceanography.
