Ludworth Intake (grid reference SJ994911) is a 5.1-hectare (13-acre) geological Site of Special Scientific Interest at Ludworth on the border of Derbyshire and Greater Manchester, England. It was notified in 1998 for its geological interest.[1]

The site, north-east of Marple Bridge and south of Chisworth, comprises a sinuous dry valley running for about 400 metres (1,300 ft) south from Intakes Farm, cutting through a broad ridge running east–west.[2] It is considered to have been formed by a meltwater stream running beside or below a glacier. Pollen analyses from the site show that the channel dates from before the Younger Dryas (around 12,900 to 11,700 years BP[3]). It has been described as "an exceptional and nationally important example of an isolated col channel cut by glacial meltwater" and as having "considerable potential for further study".[1] A public road, Sandhill Lane, runs parallel to the eastern side of the valley and cuts across its southern end[2] near the former Ludworth Moor Colliery, which ceased operation in the early 1980s.[4]
