The De Redin Towers are a series of small coastal watchtowers built in Malta by the Order of Saint John between 1658 and 1659. Thirteen towers were built around the coast of mainland Malta, eight of which still survive.

A watchtower or watch tower is a type of fortification used in many parts of the world. It differs from a regular tower in that its primary use is military and from a turret in that it is usually a freestanding structure. Its main purpose is to provide a high, safe place from which a sentinel or guard may observe the surrounding area. In some cases, non-military towers, such as religious towers, may also be used as watchtowers.
