Ithaque (French for Ithaca) was one of three short-lived French départements in present Greece. It came into existence after Napoleon's conquest in 1797 of the Republic of Venice, when Venetian possessions such as the Ionian islands fell to the French Directory. It included the islands of Ithaca, Kefalonia and Lefkada, as well as the cities of Preveza and Vonitsa on the adjacent mainland. Its prefecture was at Argostoli. The islands were lost to Russia in 1798 and the département was officially disbanded in 1802.
During the renewed French control of the area in 1807-1809, the département was not re-established, the constitutional form of the Septinsular Republic being kept.
