Vice-Admiral Sir Thomas Harvey, KCB (1775 – 28 May 1841) was a senior Royal Navy officer who saw service in the French Revolutionary and Napoleonic Wars and died as commander-in-chief on the West Indies Station.

The son of a senior Royal Navy officer and from a family with a long military tradition, Harvey distinguished himself under his father at the Glorious First of June and as a post-captain in his own right at Admiral John Thomas Duckworth's attempt to force the Dardanelles in 1807 and commanded numerous ships and stations in the post-war period.

Following the dispersal and then regrowth of the Navy surrounding the Peace of Amiens in 1801, Harvey was favoured with command of ship of the line HMS Standard, which was attached to Cuthbert Collingwood's Mediterranean fleet.

Harvey had been instrumental in burning a Turkish squadron moored at the entrance to the Dardanelles, but during the return from Constantinople a round shot more than two feet in diameter crashed through Standard's lower deck, detonating a ready magazine of gun charges and killing several men before the resulting fire could be brought under control.

[1] From 1819 to 1821 Harvey was given the plum role of commander of the Sheerness guardship HMS Northumberland until in 1821 he was promoted to rear-admiral, necessitating a temporary retirement from service until a suitable position opened up.
