HMS Dreadnought was a 64-gun third rate ship of the line of the Royal Navy, launched at Blackwall Yard in 1691. She was reduced to a fourth rate in 1697. Dreadnought was rebuilt at Blackwall in 1706 as a fourth rate of 60 guns. She was enlarged in 1722, and converted into a hulk in 1740. She continued to serve in this role until 1748, when she was broken up.
