The Grade Lutter is a river of Lower Saxony, Germany.
It is one of the two headstreams of the River Lutter in the South Harz. It rises at over 660 metres on the Aschentalshalbe. It then flows mainly in a southerly direction in order to merge with the Krumme Lutter near the district Kupferhütte of Bad Lauterberg to form the Lutter.
