Kingsbury is one of the ancient parishes of Middlesex. In 1894 it became part of Wembley Urban District, but broke away from Wembley Urban District in 1900 to become an Urban District in its own right. In 1934 Kingsbury was abolished (both the parish and the Urban District) and absorbed into Wembley Urban District, which then became a Municipal Borough in 1937. Wembley Municipal Borough in turn was abolished in 1965, becoming part of the London Borough of Brent.
Kingsbury was historically a small parish in the Hundred of Gore and county of Middlesex. Until the nineteenth century it was largely rural with only scattered settlements. Oliver Goldsmith lived at Hyde Farm in Kingsbury from 1771 to 1774. David William Murray, 3rd Earl of Mansfield was buried at St. Andrew's churchyard in 1840.
Although it lay close to London, development started slowly, and it was not until after World War I that the district became built up. An aircraft industry was established in the part of Kingsbury adjacent to Hendon aerdrome during the war, while the road network was improved to cater for the British Empire Exhibition in nearby Wembley in 1924. The number of inhabited houses in the civil parish increased from just 140 in 1901 to 3,937 in 1931. By 1951 this had risen to 11,776. Between 1921 and 1931 Kingsbury's population increased by 796%.
From 1923 to 1979 Kingsbury Road was the location of the Vanden Plas specialist motor body works, body makers for Bentley and later part of Austin, BMC, and British Leyland. The site is now Kingsbury Trading Estate. In 1894 Kingsbury was included in the urban district of Wembley. However as Kingsbury had only three councillors on the urban district council to Wembley's nine, Kingsbury's councillors felt the needs of the area were not well-served. In 1900 Kingsbury became a separate urban district with six councillors. The new council was immediately involved in controversy and in 1906 it failed to make a rate or meet its financial commitments. Following an inquiry initiated by ratepayers the council was increased to nine councillors, although personal difficulties between councillors continued for some years.
In 1934 the Kingsbury Urban District was abolished and merged once more in Wembley Urban District. The urban district became a municipal borough in 1937 and in 1965 the area became part of the London Borough of Brent.
