Marina Nani (circa 1400–1473) was a Dogaressa of Venice by marriage to the Doge Francesco Foscari (r. 1423–1457).
[2] In 1445 her son Jacopo was accused of high treason and bribery, and her spouse was forced to have him exiled.
This caused Francesco a depression, which made Pietro Loredani accuse him of being unsuitable for his office.
The authorities wished to give him a state funeral because he was popular and the public was not aware of how he had been deposed.
Maria Nani had a long widowhood and lived a peaceful life on substantial land she had inherited.
