Saint Julian's Tower (Maltese: Torri ta' San Ġiljan), originally known as Torre di San Giuliano[1] and also known as Sliema Tower (Maltese: Torri tas-Sliema),[2] is a small watchtower in Sliema, Malta.

It follows the standard design of the De Redin towers, having a square plan with two floors and a turret on the roof.

A free standing wall and a redan pierced with musketry loopholes enclosed the tower's land front, which was also protected by a shallow rock hewn ditch.

In 1798, during the Maltese uprising against the French, insurgents led by Vincenzo Borg captured Saint Julian's Tower and Battery.

[4] In 1951, the Government of Malta affixed a marble plaque on the tower with the coat-of-arms of the GrandMaster who built it.
