Renato Ziggiotti was a Roman Catholic priest of the Salesians of Don Bosco, who was the fifth Rector Major of that order, serving between 1952 and 1965. Before becoming a Salesian religious, Ziggiotti was in the military. He was the last Salesian Superior before the Second Vatican Council and the first Superior to resign the position in the Salesian history – all his predecessors died incumbent. He was also the first Rector Major to visit all the countries where there were Salesians present in the five continents, at a time when international transport was very limited.
