Grendon Underwood is a village and civil parish in Aylesbury Vale district in Buckinghamshire, England. It is in the west of the county, close to the boundary with Oxfordshire and near the Roman road Akeman Street now known as the A41. The village sits between Woodham and Edgcott and has a population of approximately 1500 (in 2012).
The toponym is derived from the Old English for 'green hill near a wood', though the 'Underwood' part of the name was only added in the medieval period to differentiate the village from nearby Long Crendon and to signify the village's position close to the Bernwood Forest. The Domesday Book of 1086 records the village as Grennedone. The manor of Grendon anciently belonged to the St Amand family. Almeric de St Amand of this family was one of the godfathers of King Edward I, who was baptised in 1239.
In 1642, Grendon Underwood lay on the forest tracks used by gypsies and strolling players (travelling performers) and was visited more than once by William Shakespeare, who stayed at the house, formerly an inn, now known as Shakespeare House, currently (2012) a five star guest house and Grade II listed, part Elizabethan former coaching inn  What Around 1809, Underwood Junction was the point at Greatmoor, just east of Grendon Underwood village, at which the Alternative Route of the London Extension of the Great Central Railway left the original main line. This was a little north of the point where the main line joined the previous Metropolitan Railway's line from Verney Junction to Aylesbury, and thence to London. The latter junction no longer exists, as the line to Verney Junction has been closed and dismantled as part of the Beeching Axe in the 1960s.
The Church of England parish church of Saint Leonard dates from the 12th or early 13th century. The village has a public house, "The Swan" specializing in Thai cuisine (correct at 2015).  Grendon Underwood Combined School is a community school with about 280 pupils. The village has a single village shop. The Grendon Garage operated in the village until 2015, when it relocated to Tingewick, near Buckingham. The former premises were demolished for redevelopment. 
Grendon Underwood once bordered Bernwood Forest, the nearest remnants of which are now Grendon Wood and Dodderhall Wood, which are detached from the village itself by approx 500 metres. Both woods are now silvicultural and classified as ancient forest and are sites of special scientific interest (SSSI's). This offers protected status to some of the endangered species of animals residing therein such as Bechstein's bats, and nightingales. There are also 35 species of butterflies such as purple emperor, brown hairstreak, black hairstreak, wood white, the silver washed fritillary, high brown fritillary, marsh fritillary, pearl-bordered fritillary and small pearly-bordered fritillary.
Grendon Underwood has two prisons, both are remotely located one mile away from the church and main village. The B-Category prison HMP Grendon is the UK's only therapeutic community for the treatment of serious offenders. HMP Grendon opened in 1962 as an experimental prison for inmates with psychiatric antisocial personality disorder. The facility holds approx 238 cat B male prisoners (April 2012). HMP Spring Hill is a D-Category open prison with an operational capacity of 335(April 2013) Indeterminate Sentenced Prisoners (ISP's). The prison building, Springhill House was a former MI6 Secret Service base during the Second World War.
