The HMS Saga ( P257 ) was a submarine of the British Royal Navy.

The saga was a boat of the fourth contract section of the successful S-Class. This is also referred to as a contract section Subtle class. She was laid on April 5, 1944 at Cammell Laird in the North West of England Birkenhead on Kiel, expired on March 14, 1945 from the pile and was put into service by the Royal Navy on 14 June 1945.

The submarine collided on October 2, 1946 at the English Channel with the trawler Girl Lena. The fishing vessel sank as a result of the accident.

The Portuguese Navy took over the HMS Saga on October 11, 1948, naming it NAUTILO. The Nautilo in 1969 transferred to the reserve.
