HMS Defence was a 74-gun third rate ship of the line of the Royal Navy, launched on 25 April 1815 at Chatham.
She was converted to serve as a prison ship in 1849. Defence was badly damaged by an accidental fire, probably caused by spontaneous combustion in a recently delivered load of coal, at Woolwich on 14 July 1857.</ref> The fire was extinguished by scuttling the ship. and while it was not totally destroyed the remains were broken up later.
