Catstye Cam is a Lake District fell of 889.6 m in Westmorland and Furness. Of the register hills in Westmorland and Furness, only Cross Fell and Nethermost Pike stand higher.
Its drop of 62.4 m makes it a Hewitt but is short of the 150 m a Marilyn needs. The key col is close by, only 0.3 km to the south-west at 827.2 m. It is 238.6 m above the average height of the 103 register hills in Westmorland and Furness. Its nearest higher summit, Helvellyn, is also the hill its key col leads to.
