Firbank Fell is a hill in Cumbria between the towns of Kendal and Sedbergh that is renowned as a place where George Fox, the founder of the Religious Society of Friends (Quakers), preached.

Fox described what happened there on 13 June 1652 in this way: While others were gone to dinner, I went to a brook, got a little water, and then came and sat down on the top of a rock hard by the chapel.

It was judged there were above a thousand people; to whom I declared God's everlasting truth and Word of life freely and largely for about the space of three hours.

A plaque on the rock there commemorates the event, which is sometimes considered the beginning of the Friends movement.

Firbank Fell is now immortalised as a place of Quaker history in one of the four houses at the Quaker school Bootham School.
