Hellidon is a village and civil parish about 5 miles (8 km) south-west of Daventry in Northamptonshire, England.

[3] The long-distance Jurassic Way footpath linking Banbury, Oxfordshire, and Stamford, Lincolnshire, passes through.

The west tower survives in its medieval condition, but in 1845–1847 the nave and chancel were heavily restored for the Rev C. S. Holthouse under the Gothic Revival architect William Butterfield.

[6] Twenty years later Butterfield designed the north aisle and the parish school, both were built in 1867.

Hugh II Watts, who had foundries at Bedford and Leicester,[8] cast the fourth bell in 1615 and the second, third and tenor in 1635.

A Hellidon friendly society called the Institute, founded in 1805[11] still existed to mark its centenary in 1905.

Goods traffic commenced in 1898 and the nearest passenger station opened in March 1899 at Charwelton, about 2 miles (3 km) south-east of Hellidon.

From 1917 until 1961 the Park Gate Iron and Steel Company had a quarry about 0.5 miles (800 m) south of the village, on the boundary with Charwelton parish.

[17] From there it ran a 1.5-mile (2 km) mineral railway down the Cherwell valley to take ironstone to the main line at Charwelton station.

[18] A steam locomotive called Charwelton was built for the line in 1917, worked it until 1942, and is now preserved on the Kent and East Sussex Railway.
