The Battles of the Isonzo (known as the Isonzo Front by historians, and "Soška fronta" by the territory's mainly Slovene population) were a series of 12 battles between the Austro-Hungarian and Italian armies in World War I mostly on the territory of present-day Slovenia, and the remainder in Italy along the Isonzo River on the eastern sector of the Italian Front between June 1915 and November 1917.
