Nicolò Sagredo (18 December 1606 – 15 August 1676) was the 105th Doge of Venice, reigning from 6 February 1675 until his death less than two years later.

He was born in Venice, the son of Zaccaria Sagredo and Paola Foscari.

His family disgraced, Nicolò was unable to embark on the life of politics he might otherwise have begun at this time.

Sagredo was able to parlay his wealth and new-found respect into a series of embassies on behalf of the Most Serene Republic, before eventually becoming a Procurator of St Mark's.

Such ceremony was the only notable characteristic of his reign as Doge: in 1675, he celebrated the traditional marriage of Venice with the sea with a level of pomp and ceremony that was long remembered by Venice for its splendor.
