Willesborough is a village, now in effect a residential suburb, on the eastern side of Ashford, in the county of Kent, England.

The area is designated as the South Willesborough Dykes Site of Nature Conservation Interest (SNCI).

[2] The South Willesborough Dykes are important in terms of the geology of the area, being in the river floodplain and in supporting neutral, wet grassland species, along with Willesborough's Aylesford Green and Boys Hall forming part of the Ashford Green Corridor, although public access is otherwise limited.

Willesborough is bordered by Ashford to the west and north-west, the M20 to the north, and Sevington and the new village of Finberry to the south-east.

In 1184 Pope Lucius III wrote to the abbot of St. Augustine, Canterbury, suggesting that the parson of Willesborough retired and passed the benefice to his son who could then be free to pursue his studies.
