Docker is a civil parish in the Westmorland and Furness district of the English county of Cumbria.

[1] In 1870–1872, John Marius Wilson from the Imperial Gazetteer of England and Wales described Docker as: "a township in Kendal parish, Westmoreland; near the river Mint and the Lancaster and Carlisle railway 3 miles ENE of Kendal"[3] Diana Whalley's A Dictionary of Lake District Place-Names (English Place Name Society 2006) has this name either as meaning "the shieling at the hollow" or "the shieling where the plant called dock grows" (from Old Norse erg = "summer pasture", taken from Irish airge), or as a personal name which "may have been a link with the family traced in Parker 1918" (Parker C.A.

It may have been thought having a parish with a population of 55 was not significant enough and as a result the council may have changed the boundaries to even out the distribution.

The A65 runs North West from Leeds in Yorkshire through Ilkley and Skipton before terminating at Kendal in Cumbria.

The M6 Motorway runs from east of Docker from Rugby via Stoke-on-trent, Liverpool and Manchester terminating at Gretna Junction.

[5] On 24 February 2007 the 17:15 Virgin train travelling from London Euston to Glasgow Central was derailed 2 miles from Docker near the village of Grayrigg.

An inquiry found the "immediate cause" of the Grayrigg derailment was a "degraded and unsafe" set of points known as Lambrigg 2B.

[6] Following the crash, the points that caused the derailment were removed and the line is now welded continuously including the segment on the Docker Viaduct.
