Lazzaro Mocenigo was a Venetian nobleman who distinguished himself as an admiral during the Cretan War against the Ottoman Empire.

The Cretan War, also known as the War of Candia or the Fifth Ottoman–Venetian War, was a conflict between the Republic of Venice and her allies against the Ottoman Empire and the Barbary States, because it was largely fought over the island of Crete, Venice's largest and richest overseas possession. The war lasted from 1645 to 1669 and was fought in Crete, especially in the city of Candia, and in numerous naval engagements and raids around the Aegean Sea, with Dalmatia providing a secondary theater of operations.
