HMS Plantagenet (1801)

HMS Plantagenet was a 74-gun third rate ship of the line of the Royal Navy, launched on 22 October 1801 at Woolwich. She was designed by Sir William Rule as one of the 'large class' 74s, and was the only ship built to her draught. As a large 74, she carried 24 pdrs on her upper gun deck instead of the 18 pdrs found on the middling and common class 74s.

Plantagenet was broken up in 1817.
