Nicolò Gradenigo (Nicoletto)

Nicolò Gradenigo, called Nicoletto (c. 1267–c. 1317), was a Venetian noble, a son of Doge Pietro Gradenigo and Tommasina Morosini.

Genealogists name Bertucci, Giacomo and Paolo as his brothers, but only Nicolò and Marco survived their father, and the two were the sole fidecommissari, the trustees of the family inheritance, named in the doge's will in 1311; no public office of his is recorded.
