HMS Blenheim was a 74-gun third rate ship of the line of the Royal Navy, launched on 31 May 1813 at Deptford Dockyard. She was placed on harbour service in 1831. Her captain, Humphrey Fleming Senhouse, died on board Blenheim in the morning of 13 June 1841, from fever contracted during operations in Canton in May 1841. In 1854/5 she saw service in the Baltic as a 60-gun steam screw. During this service she received a 32-pound cannonball to her mast. Blenheim was eventually broken up in 1865.
