Navestock is a civil parish in the Borough of Brentwood in south Essex, in the East of England region of the United Kingdom. It is located approximately 5 km (3.1 mi) northwest of the town of Brentwood and the M25 motorway cuts through the western edge of the parish. It covers an area of in excess of 1800 hectares (4500 acres) and had a population of 510 in 2001. The name means ‘the stump on the headland’, which reflects its topography and landscape.
The western edge of the parish was within the ancient forest of Essex, and two boundary stones still mark its limits. Enclosure of common land took place in 1770. Navestock was an early centre for cricket, which has been played on the green at Navestock Side since the 18th century.
According to the census of 1801 the population of Navestock was 623, and reached a peak of 982 in 1851. There was then a gradual decline in population during the period of agricultural depression in the late 19th century and the 1901 census recorded only 692 inhabitants. After fluctuating at around that level in the first half of the 20th century the population has declined further and was only 510 in 2001. This makes Navestock unusual in that despite its proximity to London its population is below its level of two hundred years ago.
