HMS Torbay is a decommissioned Trafalgar-class nuclear submarine of the Royal Navy and the fourth vessel of her class. Torbay was the fifth vessel and the second submarine of the Royal Navy to be named after Torbay in Devon, England. The first vessel was the 80-gun second rate HMS Torbay launched in 1693.

She was the first vessel to be fitted with the new command system SMCS NG.

Torbay was scheduled to be decommissioned in 2015, to be replaced by one of the new Astute-class submarines.^[3] As of November 2013^[update] she was undergoing extended maintenance and upgrades. The work allowed for a two-year life extension beyond the previously-planned decommissioning date. On 6 June 2017, she entered Gibraltar Naval Base flying her paying-off pennant and, on Friday 14 July 2017, the vessel was decommissioned in Devonport.
