The River Babingley is a chalk stream and minor river in the northwest of Norfolk in England. It runs 12.2 miles (19.6 km) from its source at Flitcham to the River Great Ouse at Wootton Marshes where it terminates.

Chalk streams are rivers that rise from springs in landscapes with chalk bedrock. Since chalk is permeable, water percolates easily through the ground to the water table and chalk streams therefore receive little surface runoff. As a result, the water in the streams contains little organic matter and sediment and is generally very clear.
