Dentdale is a dale or valley in the north-west of the Yorkshire Dales National Park in Cumbria (historically in Yorkshire), England. The dale is the valley of the River Dee, but takes its name from the village of Dent. The dale runs east to west starting at Dent Head which is the location of a railway viaduct on the Settle-Carlisle Line.
Dentdale is one of the few of the Yorkshire Dales that drain westwards towards the Irish Sea.
Dentdale was first settled in the 10th century when Norse invaders first entered the dale. The dale was also known to the Romans although there is no evidence of settlement during that period. The dale was one of the last of the Yorkshire Dales to be Enclosed in 1859.
The typical occupations in the dale were farming and worsted related. Several mills used the fast flowing waters of the River Dee to supply power to the mills. At least one of these was converted to the Dent Marble industry by 1810. Whilst fishing on the Dee at Dentdale in the 1840s, William Armstrong saw a waterwheel in action, supplying power to a marble quarry. It struck Armstrong that much of the available power was being wasted and it inspired him to design a successful hydraulic engine which began the accumulation of his wealth and industrial empire.
