Hailey is a village and civil parish about 2 miles (3 km) north of Witney, Oxfordshire.

Hailey Manor at Delly End is an ashlar-fronted early Georgian house of six bays.

[5] It was demolished and replaced by the present Gothic Revival parish church of St John the Evangelist in 1866–69.

It was designed by the young Gothic Revival architect Clapton Crabb Rolfe, whose father Rev.

But Sherwood and Pevsner describe the result as "still odd... a fantastic Gothic in colourful materials with bulbous forms and freakish detail".

[5] The ancient Wychwood royal forest included the whole of Hailey, and the northern part of the parish was mostly woodland, wood-pasture and heath.

The endings of local toponyms including Delly, Hailey and Poffley all come from leah, Middle English for a "clearing".

From the early 17th century, trades including fulling or tucking, broadweaving and clothing are frequently recorded in Hailey.

[9] The Early family of Witney blanket-makers were renting at least part of the mill by 1818 and operating the whole premises by the 1820s.

[10] Hailey Primary School[11] was founded by the charitable bequest of a local farmer's widow, Joan Smith, in 1661.

By the 1820s Joan Smith's endowment paid for the education of only 16 of the pupils, and the parents of the remainder had to pay fees.

John Williams Clinch of Witney, who was a banker and brewer, gave land next to the Lamb and Flag Inn on which to build a new school.

The architect was Clapton Crabb Rolfe, who had designed the parish church and was William Wilkinson's nephew.
