Kingsthorpe was once a Northamptonshire country village, but is now an affluent suburb to the north-west of the county town of Northampton, England. Kingsthorpe became part of the borough of Northampton in 1900. A tributary of the River Nene known as the Naseby Source or Brampton Nene flows through the area to the west from north to south, joining the main river west of the Carslberg Brewery near the south bridge. The suburb's facilities are centred on the main A508 and A5199 roads between Northampton town centre and leading to Market Harborough and Leicester respectively. The original village green still maintains a rural character, away from the major roads, overlooked by the church and picturesque vernacular cottages. Kingsthorpe originally had three water mills, some evidence of which can be found in the countryside around the suburb.
