Little Hart Crag is a Lake District fell of 637 m in Westmorland and Furness. It rises only 34 m above its key col, 5.3% of its height.
Its key col leads to Fairfield, not to its nearest higher summit, Middle Dodd. It shares its height of 637 m with Causey Pike and Knocknamanagh. On the Wainwrights height ladder it sits between Causey Pike (637 m) and Starling Dodd (633 m). Its drop of 34 m makes it a Hewitt but is short of the 150 m a Marilyn needs. The key col is close by, only 0.4 km to the north-west at 603 m. Its other name is Little Hart Crag - West Top.
