Valdrada (Gualdrada) of Tuscany (died 997) was a Dogaressa of Venice by marriage to the Doge Pietro IV Candiano (r. 959–976).
She was arranged to be married to Pietro by Emperor Otto III after the divorce of his former dogaressa, Giovanniccia Candiano.
She supported his ambitions and strengthened his status by behaving as a Queen, and was reportedly the first dogaressa to follow a royal ceremonial protocol.
[2] Slavery became a controversial issue in Venice because of her retinue of slaves, but when her spouse asked her to free them, she replied that she was a subject of the emperor, but not of the doge.
They set fire to the residence of the Doge and the family fled he with their small son Pietro in his arms, she with her daughter Marina in hers.
