Federico Baldissera Bartolomeo Cornaro (16 November 1579 – 5 June 1653) was a Venetian Catholic Cardinal and Patriarch of Venice.

In February 1623, he was elected Bishop of Bergamo, but retained the clericate of the Apostolic Chamber, and was consecrated in April by Cardinal Marcantonio Gozzadini.

Three years later he was elevated to Cardinal by Pope Urban VIII and was installed as Cardinal-Priest of Santa Maria in Traspontina and appointed Bishop of Venice.

His elevation was not without controversy as the Republic of Venice prohibited any son of a Doge from accepting a papal appointment.

Cornaro was appointed Cardinal-Priest of Santa Cecilia in Trastevere in 1627 and San Marco in 1629 before being promoted to Patriarch of Venice in June 1631, a position he held until 1644.
