High Raise (High Street) is a Lake District fell of 803.6 m in Westmorland and Furness. It overtops all four of its nearest neighbours; the tallest of them, Rampsgill Head, reaches 792.4 m.
Its drop of 89.9 m makes it a Hewitt but is short of the 150 m a Marilyn needs. Its nearest higher summit, High Street, is also the hill its key col leads to.
