Budby is a small hamlet in Nottinghamshire. It is located 3.5 kilometres north of Edwinstowe, and is in the civil parish of Perlethorpe-cum-Budby. Nearby is Thoresby Hall, the former home of the Earl Manvers.
The hamlet itself is located by the A616 and the River Meden. Budby dates to at least 1662 when the area was part of Sherwood Forest then a Royal Forest, though most of the forest has since been cleared for agriculture. It consists of two farms and 13 cottages built for farm workers some of which are still used by employees of the various farms in the area. It contains a Post Box dating to the reign of Queen Victoria which may be one of the oldest in the country.
