Fra' Alof de Wignacourt (1547 – 14 September 1622) was the 54th Grand Master of the Order of Malta, from 1601 to 1622. He was of the langue of France. His reign was notable for the construction of a number of coastal fortifications (the Wignacourt towers), and of the aqueduct that brought water from the plateau above Rabat to Valletta. His parade armour survives and is one of the treasures of the Palace Armoury in Valletta. He was briefly a patron of the painter Caravaggio.
