HMS L1 was a British L-class submarine built by Vickers, Barrow. Originally laid down as E-class submarine E57 on 18 May 1916, she and sister ship E58 incorporated enough changes that they were renamed as the first pair of boats of a newly designated L class. L1 was launched 10 May 1917, and commissioned on 10 November 1917.

She sailed to Hong Kong in 1919. L1 was placed in the reserve flotilla in 1923 in Hong Kong. She was then sold in March 1930 and sold for scrap. While being towed to Newport she broke free and was stranded at Penanwell Cove, near Porth Nanven in Cornwall. She was scrapped where she lay. Some metal remains can still be seen there on low spring tides.
