Greek frigate Elli (F450) () is the lead ship of the Greek Elli class of frigates and the third Hellenic Navy ship by that 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 its class in the Hellenic Navy, it was not originally in Dutch service, but was sold directly to Greece. The Elli took part in the Persian Gulf War from 1990–91, enforcing the UN resolution on Iraq in the neighborhood of the Red Sea.
