Kings Langley is a village, former manor and civil parish in Hertfordshire, England, 23.5 miles (37.8 kilometres) north-west of London and to the south of the Chiltern Hills.

Following the Norman Conquest of 1066 the manor was one of hundreds given to Robert, Count of Mortain, uterine half-brother of King William the Conqueror.

There are many businesses located near the station in Home Park Industrial Estate which is also the site of the Construction and Engineering Centre of West Herts College.

During the Second World War, the village was home to the secret headquarters in Britain of the Polish Underground army based at Barnes Lodge just off the Hempstead Road near Rucklers Lane.

The complex incorporates a highly visible 225 kW Vestas V29[11] wind turbine, nicknamed "Lofty" alongside the M25.

[12] The M25, the London orbital motorway, passes just south of the village on an imposing viaduct across the River Gade valley.

To the north of junction 20 with the A41, a dual-carriageway bypasses Kings Langley and continues to the south of Tring where it flows into the original motorway-standard by-pass.

Just to the north of Kings Langley is a small village called Rucklers Lane, named after the road it is built on.

The origin of the settlement in the early 20th century was the construction of a number of mock tudor houses for the workers on the nearby Shendish Manor estate.

A community hall was also built for the workers in 1909 as a memorial to Arthur Longman, the owner of the estate; it was originally intended as a chapel of ease to avoid the long walk to the parish church.
