The Third Ottoman Venetian War (1537–1540) was one of the Ottoman–Venetian wars which took place during the 16th century. The war arose out of the Franco-Ottoman alliance between Francis I of France and Süleyman I of the Ottoman Empire against the Holy Roman Emperor Charles V. The initial plan between the two had been to jointly invade Italy, Francis through Lombardy in the North and Süleyman through Apulia to the South. However, the proposed invasion failed to take place.
