Lodovico Flangini (Venice, 1677 – 22 June 1717) was a Venetian noble who served as Capitano Straordinario delle Navi (commander of the sailing fleet) during the Seventh Ottoman–Venetian War.

Already as a youth he enlisted in the Venetian navy and participated in the War of the Morea in 1696–1697 as a ship of the line captain (Governator di Nave) under the provveditore Grimani.

Flangini hoisted his ensign on the newly built 70-cannon battleship Leon Trionfante, and on 12 May scored a partial victory at the Battle of Imbros, in which he forced the Ottoman fleet of 42 ships to retreat.

[6] Four days later, the two fleets met again in the sea between Mount Athos and the island of Agios Efstratios, and in the ensuing battle, the Venetians defeated the Ottomans.

Heavily wounded, he sailed to Thermia (Kythnos), but again led the Venetian fleet in battle on 22 June, directing the action from the deck of his flagship until he collapsed and died.
