The Mochuritsa is a river in southern Bulgaria, a left tributary of the river Tundzha of the Maritsa drainage, with a length of 86 km. It is the largest tributary of the Tundzha.
The river takes its source at an altitude of 561 m on the southern foothills of the Stidovska planina section of the Balkan Mountains, in the vicinity of the Novo Selo Range. Along its entire length, it flows through flat terrain in a wide valley with a large flood terrace and a small longitudinal slope of 1.4 %. In its upper course, it crosses from west to east the Sungurlare field of the Karnobat Valley, while gradually turning southwards. West of the town of Karnobat, it turns in a southwesterly direction and forms a short gorge between the Terziyski Ridge to the west and the Hisar Heights to the east. Downstream of the gorge, the Mochuritsa enters the Sliven Valley, where its longitudinal slope becomes even smaller and marshy areas and high groundwater appear in its valley, which gives the name of the river from the Bulgarian word for marsh, мочурище (translit. mochurishte). It flows into the Tundzha at an altitude of 128 m in the north industrial zone of the city of Yambol.
Its drainage basin covers a territory of 1278 km2.
