Fleetwith Pike is a fell in the English Lake District in the county of Cumbria which reaches a height of 648 metres (2,126 feet).

It is bounded by Honister Pass to the north and Warnscale Bottom to the south-west, their two streams uniting beneath the fell in Buttermere.

Fleetwith Pike is lined on all sides by impressive crags, other than for the broad plateau leading across the Drum House to Grey Knotts.

Honister Crag was upgraded to become a Nuttall fell in November 2004, the first addition to the list since they were first published in 1990, it has 20 metres (66 feet) of topographical prominence from Fleetwith Pike.

This route goes past a white cross which is clearly visible from the valley and bears the inscription "Erected by Friends of Fanny Mercer, accidentally killed 1887".
