Comino (Kemmuna) is a small island of the Maltese archipelago between the islands of Malta and Gozo in the Mediterranean Sea, measuring in area. Named after the cumin seed, the island has a permanent population of only two residents and is part of the municipality of Għajnsielem, in southeastern Gozo, from where one priest and one policeman commute. The island is a bird sanctuary and nature reserve (Natura 2000 marine protected area).
The island has a karst landscape supporting sclerophyllous shrubland. Some limited afforestation with pine trees has been carried out. The sand-dunes at Santa Maria bay retain some native vegetation, including Vitex and Tamarix trees. The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports fifty to eighty breeding pairs of yelkouan shearwaters.
Formerly called Ephaestia (Ηφαιστεία in Ancient Greek), Comino is known to have been inhabited by farmers during Roman times, but for long periods in its history it has been sparsely populated, privately owned, or abandoned entirely. Its rugged coastline is delineated by sheer limestone cliffs, and dotted with deep caves which were popular with pirates and marauders in the Middle Ages. The caves and coves of Comino were frequently used as staging posts for raids on hapless boats crossing between Malta and Gozo. From 1285 until some time after 1290, Comino was the home of exiled Jewish prophet and Kabbalist Abraham Abulafia. It was on Comino that Abulafia composed his Sefer ha-Ot (The Book of the Sign), and his last work, Imre Shefer (Words of Beauty).
In later years, the Knights of Malta used this island as hunting and recreational grounds. The Knights were fiercely protective of the local game, which consisted of wild boar and hares (Maltese: fenek tal-grixti): upon conviction, poachers were liable to a penalty of three years as a galley slave. In the 16th and 17th centuries, Comino served as a place of imprisonment or exile for errant knights.
