Dojran Lake, also spelled Doiran Lake is a lake with an area of 43.1 km2 shared between North Macedonia and Greece.
To the west is the city of Nov Dojran, to the east the village of Mouries, to the north the mountain Belasica/Beles and to the south the Greek town of Doirani. The lake has a rounded shape, a maximum depth of 10 m and a north-to-south length of 8.9 km and is 7.1 km at its widest, making it the third largest lake partially in North Macedonia after Lake Ohrid and Lake Prespa.
The lake was on the southern line of the Macedonian front during World War I, and its southern shore became the site of the various battles between allied troops and Bulgarian troops in 1916, 1917 and 1918. A monument to one of the battles and two cemeteries for Greek and British troops stand on a hill a few hundred metres south of the lake. It was designed by Sir Robert Lorimer.
