Balkan Entente (äntänt´), loose alliance formed in 1934 by Yugoslavia, Romania, Greece, and Turkey to safeguard their territorial integrity against Bulgarian revisionism. It thus was in harmony with the Little Entente (formed by Yugoslavia, Romania, and Czechoslovakia chiefly against Hungarian revisionism). The events of World War II caused the dissolution of the Balkan Entente.
