Easington (/ˈɛzɪŋtən/) is a civil parish within the Ribble Valley district of Lancashire, England, with a population in 2001 of 52. The Census 2011 population details have been grouped with the parish of Slaidburn. Before 1974, it formed part of Bowland Rural District in the West Riding of Yorkshire. It covers just over 9000 acres.

The parish adjoins the Ribble Valley parishes of Bowland Forest High, Slaidburn, Grindleton, Bolton-by-Bowland and Gisburn Forest along with Tatham in the City of Lancaster district and also Clapham cum Newby, Austwick, Lawkland and Giggleswick in the county of North Yorkshire.

Near Brown Hills Beck on the eastern border of the parish is a bowl barrow thought to date from the late Neolithic or Bronze Age periods. It is an oval mound of earth, 25 by 15 metres (82 by 49 ft) wide and up to 8 metres (26 ft) high. There is another similar mound on the opposite side of the stream in Gisburn Forest.

Part of the Forest of Bowland, the historic township had two divisions—Lower and Upper Easington—which are geographically non-contiguous. Mystery surrounds the origin of these two divisions.

From Norman times, Lower Easington formed part of the Liberty of Bowland, being a possession of the Lords of Bowland. Its manor was subinfeuded and by the thirteenth century was held by the De Wannervill family. Ownership passed to the Bannister family in the early sixteenth century, with the manor eventually being broken up and sold off piecemeal in the 1690s. The manor sat due south of Slaidburn within the modern-day township of Newton-in-Bowland.

Upper Easington is the larger of the two divisions and includes Dalehead and Stocks Reservoir. It abuts Gisburn Forest and marks the easternmost extent of ancient Bowland. To the north of Upper Easington sits the Cross o'Greet, the ancient boundary point and watershed between the medieval lordships of Bowland and Burton-in-Lonsdale, Clitheroe and Hornby; the route up to the Cross across what was anciently called "Gradale" is perhaps one of the most ruggedly beautiful in the Forest.

It is thought that the lands of Upper Easington may originally have been part of the Slaidburn township but grants by the de Lacys to Kirkstall Abbey in the twelfth and thirteenth centuries gave the area its own distinctive identity. The township of Rushton was granted by Robert de Lacy, 3rd Lord of Bowland, in 1180. This was to be the site of the area's monastic grange (now submerged beneath Stocks Reservoir). In 1220 or thereabouts, John de Lacy, 5th Lord of Bowland, granted an area west of the Hodder and north of Rushton known as "Gamellesarges". In Helen Wallbank's unpublished translation from the Latin, the description of Upper Easington from the grant of 1232–40 reads:

all the land with woods and pasture, without reservation ... on the eastern part of the water of the Hodder in Bowland, just as the water of Hodder descends to the higher head of Gradalehals by the grange of the aforesaid monks as far as the town of Riston, and from the aforesaid head of Gradalehals to the higher head of Kesedene by the boundaries and divisions between my fee and the fee of William de Mowbray, and from the high head of Kesedene to the high head of Rowenumcnothes, and from the high head of Rowenumcnothes as far as the eastern head of Rowenumcnothes, and from the eastern head of Rowenumcnothes, as far as the high head of Hesbrithehawebroc, according to the divisions and bounds between my fee and the fee of William de Percy, and from the high head of Hesbrithehawebroc just as the water of Hesbrithehawebroc descends to the Thirnesetegilebroc, and the Thirnesetegilebroc just as the water of Thirnesetegilebroc descends to the water of the Hodder in the town of Riston.
