Ezhimala Hill, Mountain summit in Kannur district, India

Ezhimala Hill is an isolated promontory reaching 286 metres, about 38 km north of Kannur near Payyanur. Its slopes hold the Indian Naval Academy, Asia's largest and the world's third-largest naval academy, while a lighthouse stands on Mount Deli, the hill's highest peak.

Ezhimala was the capital of the Mushika dynasty, whose first king Ramaghatamushika ruled from the hill; the dynasty later became the Kolathiris. The most famous ruler, Nannan, was killed by the Chera king Narmudi Cheral at the battle of Vakaip Perumthurai, after which Poozhinadu passed to the Cheras. In the 11th century the hill was a major battlefield of the Chola-Chera wars.

The hill's name comes from Malayalam 'Eli Mala', meaning high mountain, which was mistranslated as 'Seven Hills' in a local Sanskrit text, giving the name Sapta Sailam. Arab sailors called it Ras Haili, the Portuguese Monte d'Eli and the British Mount Delly. A saying still current in the area holds that Nannan's treasures were eaten by jackals and dogs.

Ezhimala railway station exists but trains do not stop there; the useful stations are Payyanur, about 9 km to the north-west, and Pazhayangadi, about 10 km east. The lighthouse on Mount Deli is maintained by the Indian Navy and entry is restricted. Dolphins can be seen off Ettikulam beach at the southern end of the hill.

The Indian Naval Academy at Ezhimala is Asia's largest and the world's third-largest naval academy. The site was chosen by K. P. Achutha Menon, former Defence Secretary of India. The academy occupies the hill that Arab sailors called Ras Haili and the British Mount Delly.
