Calf Top is a mountain in the western part of the Yorkshire Dales, England.

Calf Top is a dominating profile in the view from many of the smaller hills to its west, such as Lambrigg Fell and Hutton Roof Crags.

Calf Top is separated from its neighbours, Great Coum and Aye Gill Pike by the deep trench of Barbondale, meaning that although it is lower than most of the hills in its region, it has high relative height and is a Marilyn.

The closeness of this figure to the threshold of 2,000 feet (609.6 m) used in the United Kingdom to separate mountains and hills led to the summit being surveyed using precision GPS and levelling equipment.

[5] This resulted in a height of 609.606 metres, thus updating the status of Calf Top from hill to mountain.
