Kingsbrook is a housing development and civil parish to the north-east of Aylesbury in Buckinghamshire, England, around 1.6 miles (2.5 km) from the town centre and almost contiguous with the town.

Kingsbrook comprises mostly new build housing in the "Oakfield Village", "Canal Quarter" and "Orchard Green" neighbourhoods, each described by the developers as a village. Its first primary school opened in September 2021 and the secondary school opened the following year. A second primary school, Orchard View, will open in 2026. Development started in early 2016.

The parish was established in 2020 when the former parish of Bierton with Broughton was divided into three.

Kingsbrook is served by Arriva buses X4 and X14 between Aylesbury, Leighton Buzzard and Milton Keynes.
