Ghajnsielem, meaning "Spring of Peace", is a municipality on the southeastern coast of the island of Gozo in Malta, including the entire island of Comino. It has a population of 2,570 residents (2005 census) and is the first Gozitan village that greets the visitor on leaving Mgarr Harbour towards the Gozitan heartland.

Its name originated from the water spring, around which in 1700, Grandmaster Perellos built an arcade containing public washbasins and fresh water spouts. One could not remain anything less than charmed by the views upon the Gozo Channel particularly early in the morning or late at sunset.
