Mixbury is a village and civil parish in Oxfordshire, about 2.5 miles (4 km) southeast of Brackley in Northamptonshire.

[3][4] The Domesday Book records that in 1086 Roger d'Ivry held a manor of 17 hides at Missberie.

Evidence suggests that it may have begun with two fields, but by the latter part of the 17th century it had been reorganised as a more efficient three-field system.

[1] The original village consisted of thatch-roofed rubblestone cottages clustered between All Saints and the stream.

[12] In 1874 they were demolished under an order of the Court of Chancery and replaced with two rows of brick-faced semi-detached estate cottages laid out as a model village along the road leading south from the church.

[12] In 1847–50 the Buckinghamshire Railway built its branch line to Banbury Merton Street through the northern part of the parish along the Great Ouse Valley.

Fulwell & Westbury station was built on the line about 1 mile (1.6 km) northeast of the village.

The Great Central Main Line from Nottingham Victoria to London Marylebone was built through the eastern part of the parish in the 1890s and opened in 1899.
