The River Thet is a river in Norfolk, England and is a tributary of the River Little Ouse.It rises in Breckland with sources in Deopham Green and Rockland All Saints[1] and joins the Little Ouse in Thetford after flowing approximately southwest.

[2] The primary sources for its various small tributaries include the calcareous valley fen SSSIs Swangey Fen,[3] Old Buckenham Fen,[4] Middle Harling Fen[5] and Kenninghall and Banham Fens with Quidenham Mere.[6]Carr woodland is also a prevalent habitat throughout the floodplain where open wetlands have been invaded by scrub. The underlying geology is clay/loam over chalk for the easternmost parts of the river's course and sand/gravel over chalk for the majority of the river.
