Kudiramalai ( Sinhala: කුදිරමලෙයි, Tamil: குதிரைமலை, Greek: Hippuros, English: Horse Mountain) is a cape and ancient port town on the west coast of Sri Lanka. On the Gulf of Mannar near Silavaturai, the town shares a history with nearby Karaitivu Island, the ancient port town of Mannar and the Ketheeswaram temple. Kudiramalai is the northernmost point of Puttalam District and was a southern port of Mannar during the classical period, serving the northern kingdoms of the Jaffna Peninsula and Vanni country as one of their southernmost border towns. It is west of Vanni from Trincomalee (Thiru-Konamalai), home of Koneswaram temple.
Rulers included Alli Arasani, Korran, his father (Pittan) and contemporaries, Athiyamān Nedumān Añci (father and son) and Kumanan. Traders brought several horses on watercraft to the island during the Sangam period. The port was known as Hippuros by the ancient Greeks, and was mentioned in Ptolemy's Periplus of the Erythraean Sea. Archaeological excavations have found that Kudiramalai was inhabited from the first century BCE to the seventh century CE.
