The Helvellyn range is the name given to a part of the Eastern Fells in the English Lake District, “fell” being the local word for “hill”. The name comes from Helvellyn, the highest summit of the group.

The Helvellyn range forms a ridge extending for about 10 km, at no point dropping below 600 m. The ridge runs in a north–south direction, with Patterdale on the eastern side and the Thirlmere valley to the west. The village of Threlkeld lies directly to the north, below the northernmost point on the ridge, Clough Head.

Generally, the slopes above Thirlmere are steep and grassy, whilst the Patterdale side exhibits rockier features, due to cirque glaciation on the north east side of the ridge.
