The River Little Ouse, also known as the Brandon River, is a river in the east of England, a tributary of the River Great Ouse. For much of its length it defines the boundary between Norfolk and Suffolk.

According to the official environment data, it rises south east of Botesdale, on the civil parish border to Burgate. In Openstreetmap, the source has erraneously been mapped at B 1113 Road east of Thelnetham, close to the source of the River Waveney. The officially defined headwater is marked in OSM, too, but unlabelled. The village of Blo' Norton owes its name to the river: it was earlier known as Norton Bell-'eau, from being situated near this "fair stream". In this area the river creates a number of important wetland areas such as at Blo' Norton and Thelnetham Fens, and areas managed by the Little Ouse Headwaters Project. The course continues through Rushford, Thetford, Brandon, and Hockwold before the river joins the Great Ouse north of Littleport in Cambridgeshire. The total length is about 37 miles (60 km).

The river is navigable from the Great Ouse to a point 2 miles (3.2 km) above Brandon.
