Culworth is a village and civil parish about 7 miles (11 km) north of Brackley in South Northamptonshire, England. Culworth is also about 7 miles (11 km) northeast of the north Oxfordshire town of Banbury.
The village stands on the brow of a hill about 540 feet (160 m) above sea level. The 2011 Census recorded the parish's population as 445.
A third-century Roman coin from the brief reign of the Roman emperor Quintillus was found in the parish before 1841.
Berry Hill, just north of the parish church, is a medieval ringwork, built probably late in the 11th century. It is a scheduled monument. On its southwest side, part of its circular ditch was cut away in the 19th century to make the garden of the Old Rectory, but otherwise it survives intact. There are similar ringworks at Sulgrave, Weedon Lois and Weston.
William de Culworth was sheriff of Hertfordshire and Constable of Hertford Castle in 1230 and 1234.
