Weldon is a suburban village and civil parish on the eastern outskirts of Corby, Northamptonshire, England. It is two miles away from Corby. The village is listed in the Domesday Book as 'Weledene', in the Colby Hundred. The head of the manor before 1066 is listed as 'Weldon', likely Anglo-Saxon. The Lord in 1066 is listed as 'Northmann', perhaps an unnamed Viking or Dane. The Lord, and Tenant-in-Chief, in 1086 was Robert de Bucy (Buci), a Norman.
The village's name means 'hill with a spring/stream'.It is, currently, administered by North Northamptonshire council. Prior to local government changes in 2021 it was administered by Corby Borough Council; at the time of the 2001 census, the parish's population was 1,644 people, increasing to 2,099 at the 2011 Census.Weldon is at the crossroads of the north–south A43 trunk road which bypasses it to the west and the A427 that, locally, provides a route to Market Harborough westbound and Oundle eastbound; traffic on this road is "calmed" by an extensive scheme. The King's Arms public house was demolished and replaced with housing.
