Castleton is a village in the High Peak district of Derbyshire, England, at the western end of the Hope Valley on the Peakshole Water, a tributary of the River Noe, between the Dark Peak to the north and the White Peak to the south. The population was 642 at the 2011 Census.

Castleton village was mentioned as Pechesers in Domesday Book in 1086 where "Arnbiorn and Hundingr held the land of William Peverel's castle in Castleton". This land and Peverel's castle were amongst the manors belonging to William Peverel that also included Bolsover and Glapwell.
A medieval leper hospital (the Hospital of Saint Mary in the Peak) is thought to have been on the eastern boundary of Castleton, though some locals believe it to have been just south of the Speedwell Cavern footpath from the village. Sheffield University archaeologists are investigating ‘Castle of the Peak’, which was reputedly founded by the wife of one of the William Peverels before 1153, and continued until about the 1543 Dissolution. They say the earliest documents referring to Spital Field are a grant and a Charter from the early 14th century. They are also investigating the 12th-century planned town at the foot of the castle hill.
Castleton later prospered from lead mining; the Odin Mine, one of the oldest lead mines in the country, is situated 1.5 kilometres (0.9 mi) west of the village (see also Derbyshire lead mining history). This created and enlarged local caverns, four of which are now open to the public as Peak Cavern, Blue John Cavern, Speedwell Cavern and Treak Cliff Cavern. A small amount of Blue John is mined locally.
Castleton is situated between the gritstone plateau of the Dark Peak to the north and the gentler limestone scenery of the White Peak to the south. It lies at the western end of the Hope Valley and consequently is surrounded on three sides by hills. Most prominent is the ridge to the north. This is called Great Ridge; it runs east from Mam Tor to Back Tor and Lose Hill, via the pass (hause) of Hollins Cross, where paths from many directions converge and cross over to Edale. Alexander von Humboldt visited caves near Castleton and Buxton in June 1790 to investigate the region's geological structures.
Castleton used to be on the A625 road from Sheffield to Chapel-en-le-Frith, on the way to Manchester. Leaving Castleton, the western road used to go over Mam Tor, but after continual collapses and repairs (Mam Tor is called the "Shivering Mountain" because of its very loose shales), it was eventually abandoned.
The only westbound exit from Castleton is now the unclassified road over the narrow Winnats, more frequently called "Winnats Pass". This road is very narrow and steep and unsuitable for heavy vehicles or high volumes. Road signage has been designed to discourage through traffic by showing only local destinations. Thus, most traffic enters and leaves the village on the eastern (Hope-Hathersage-Sheffield) road; for traffic going west, that involves a long diversion via the villages of Bradwell and Peak Forest.
Caslteton Church of England Primary School is located within the village. It was rated as 'good' in its 2017 Ofsted inspection. From October 2017 the school and surrounding area was featured in the Channel 4's new ident.
The nearest secondary school is Hope Valley College.
Castleton has a small bus station from where buses depart hourly to Sheffield (services 272  and 4 times a day via Ladybower to Sheffield (273 & 274 ) and to Tideswell and Bakewell (service 173 ). A few less frequent bus services also serve Castleton, including services 68  to Buxton and 174  from Baslow, which run just once a day, 200  on schooldays to Chapel-en-le-frith and Edale and 276  on Fridays to Chesterfield.
Castleton attracts large numbers of tourists, and there are many pubs (some with accommodation), tea shops and guest houses to supply their needs. There is also a large car park, an information centre which houses Castleton Museum (closed for refurbishment until May 2017), several outdoors shops and a youth hostel. Many schools visit the area for educational studies such as GCSE fieldwork. It is also a major walking centre, where routes up Cave Dale, Winnats Pass, Mam Tor and Hollins Cross meet. There are four "show caves" to visit, Blue John Cavern, Peak Cavern, Treak Cliff Cavern and Speedwell Cavern which includes an underground boat ride and at least one of them is open all year. Castleton has a combined post office and general shop.
On Castleton Garland Day (Oak Apple Day – 29 May), a Garland King is paraded around the streets wearing an extremely large garland of flowers, followed by local girls dressed in white with flowers. The village is also famous for its display of Christmas lights and decorations during the festive season.
Castleton is popular with walkers: there is plenty of accommodation, and there are many public footpaths leading from the village. There are easy walks along the river to Hope, Brough, Bamford and (rather further) Hathersage, and there is a short strenuous walk up onto the Great Ridge, where views can be enjoyed before descending to Edale or returning to Castleton. Hayfield is a short day's walk away beyond Rushup Edge. A two- or three-day trail, the Limestone Way, starts in Castleton and runs south down Cave Dale (past the rear of the castle) before climbing out of the village and heading for Monyash, Youlgreave, and Matlock.
The village was featured in episode 3 of Most Haunted: Midsummer Murders where the team "investigates" the 18th-century murder of an engaged couple. Much of the "investigation" takes place in Speedwell Cavern. One of the conspirators, James Ashton, is said to have confessed to the murders on his deathbed after being haunted by the dead couple. He also implicated others involved. Castleton also featured in national news reports in the early 1980s following the murder of Susan Renhard near the battlements of Peveril Castle.
The local underground caves were used as the filming location for the underworld, ruled by the evil Lady of the Green Kirtle (played by Barbara Kellerman), in the 1990 BBC adaptation of The Silver Chair (one of the Narnia books written by C.S. Lewis). Cave Dale features in the films The Princess Bride (1987) and The Other Boleyn Girl (2008).
