Dunnockshaw or Dunnockshaw and Clowbridge is a civil parish in the borough of Burnley, in Lancashire, England. The parish is situated between Burnley and Rawtenstall. According to the United Kingdom Census 2011, the parish had a population of 185.

It contains the hamlets of Clowbridge and Dunnockshaw, both located on the A682 road. Clowbridge Reservoir is situated in the east of parish on the boundary with Rossendale. The reservoir, operated by United Utilities, is used as a location for water sports. It was built in 1866 resulting in the de-population of the village of Gambleside.

The parish adjoins the Burnley parishes of Hapton and Habergham Eaves and the Gambleside and Loveclough areas of the Borough of Rossendale.

The name Dunnockshaw probably comes from the words "dunnock", a small bird known locally as a hedge sparrow, and "shaw" (Old English sceaga), a small woodland or thicket.

Dunnockshaw was one of the booths in the Forest of Rossendale. By the 17th century it was the property of the Towneleys of Hurstwood, probably by inheritance from the Ormerod family. The road that is now the A682 was built by the Burnley and Edenfield Turnpike Trust following a 1795 act of Parliament, to improve transport to Manchester.

The three-storey Oak Mill was erected as a combined spinning and weaving mill in 1840 for a colliery owner and quarry master named Peter Pickup. Subsequently, extended, a fire in 1907 gutted much of the building and the interior was reconstructed. It has not been used by the textile industry since at least the early 1970s, when glass fibre products began being produced here.

Burnt Hills Colliery was owned by the Executors of John Hargreaves, operating from the 1840s until official closure in 1920. It worked the Upper and Lower Mountain mines and in 1842 employed 20 men and boys. A surface tramroad connected to Porters Gate Colliery on the north side of the hill by about 1863. In 1880 the tramroad was extended from Porters Gate to connect to the system at Hapton Valley Colliery, creating an almost 4.8-kilometre (3 mi) long route that reached the Leeds and Liverpool Canal at Gannow in Burnley. In 1892 it had two 44-metre (48 yd) shafts with a single-cylinder winding engine along with an underground engine which drove a 3.2-kilometre (2 mi) long haulage system that raised the coal through a surface drift. It is uncertain when production stopped, as after 1910 any output was recorded with Hapton Valley. The coal staithe next to Cotton Row and tramroad continued to operate for some time after 1920.

Permission to construct the reservoir at Clowbridge—historically known as the Hapton Reservoir—on the Limy Water, was contained in the 1853 that act created the Haslingden and Rawtenstall Waterworks Company. 18 months after starting construction under the supervision of Thomas Hawksley, work was suspended as the company expended all its capital. After a three-year hiatus work recommenced under the direction of Joseph Jackson, and although nearing completion in 1863, a series of landslips meant work was not completed until August 1865. The total cost was at least £46,547 (the equivalent of £5.06 million as of 2025). Later taken-over by the Bury Corporation, in 1898 it was recorded to cover an area of 88 acres (36 ha) and have a capacity of 350 million imperial gallons (1.6 million cubic metres; 1.6 billion litres). Some of its water supply is pumped from an old mineshaft belonging to the Gambleside Colliery. At the end of the 19th century a total population of 110 lived in 22 houses within the "gathering ground" of the reservoir, with Cronkshaw Hill farmhouse located very close to the shoreline. Concerns over pollution lead to increased restrictions on farming in the area.
