Tommasina Morosini

Tommasina Morosini (born in the 1260s) was a Venetian noblewoman who married Pietro Gradenigo, later doge of Venice. When he took office in 1289 she became dogaressa until her death before 1309. She was a niece of Tomasina Morosini, queen of Hungary and mother of Andrew III.

She bore Gradenigo at least ten children, including Nicolò, who served as a Venetian envoy to Treviso in 1314, and Isabetta, who married the Paduan lord Giacomo I da Carrara.
