Limnos (F451) is an Elli-class frigate of the Hellenic Navy, and the third Greek warship to bear the name. The class is based on the Royal Netherlands Navy's Kortenaer class and was built in a Dutch shipyard; however, unlike later members of her class in the Hellenic Navy, she was not originally in Dutch service, but was sold directly to Greece. Limnos was constructed in Vlissingen, Netherlands, along with her sister ship Elli. The contract for her construction was signed in Athens in July 1981 and her commissioning took place on 18 September 1982. After commissioning, Limnos joined the Hellenic Fleet on 5 November 1982 and since then she has actively participated in its activities.

The Elli-class frigates are a series of frigates operated by the Hellenic Navy. The ships are of Dutch origin and are also known as Kortenaer-class or Standard-class or S-class frigates. The first two ships, which have lengthened hangars and different armament were built specifically for the Hellenic Navy. The remaining ships are ex-Royal Netherlands Navy S-frigates of the Kortenaer class transferred to the Hellenic Navy in the 1990s and early 2000s. These robust and reliable ships constitute the backbone of the Hellenic Navy. Elli, for which the class is named, is itself named after two famous Greek cruisers, one of which was sunk during peacetime before the Greco-Italian War.
