Barrowby is a village and civil parish in the South Kesteven district of Lincolnshire, England. It lies 2 miles (3.2 km) west of Grantham town centre in a position overlooking the Vale of Belvoir. It has a Grade I listed parish church. The 2001 Census listed 795 households and a population of 1,996, which fell to 1,952 in 840 households at the 2011 census. This may reflect a fall in the size of households.
The first written records for Barrowby are in the Domesday Book of 1086, in which the village is referred to as "Bergebi", thought to derive from Scandinavian languages 'berg-by' meaning 'village by the hill'. The Domesday record shows that there was a church with a priest and 60 acres (0.24 km2) of meadow. The village belonged until the 19th century to the historical wapentake of Winnibriggs and Threo.
The Domesday village of Casthorpe is 1.5 miles (2.4 km) west from Barrowby. By the 14th century it was referred to in records as two holdings, East and West Casthorpe. It is now little more than a cluster of farm buildings. A further deserted medieval village is Newbo, 1.5 miles (2.4 km) to the north-west, which was located by archaeologists in 1970.
Barrowby is situated where the A52 road crosses the A1 road which separates the village from the western edge of Grantham. The village is close to the Lincolnshire border with Leicestershire and Nottinghamshire.
Barrowby is 300 feet (91 m) above sea level, and adjacent to the Vale of Belvoir. From the village can be seen Belvoir Castle, Lincoln Cathedral, and power stations in the Trent valley, including West Burton and Cottam, near Gainsborough over 40 miles (60 km) away.
There has been a Barrowby fête or gala in various forms since the 1950s. From 2004 until recently, an annual Barrowby Gala and Beer Festival was held on the village green. The event, with stalls, games, fairground rides, and tug of war, was organised by a committee of village residents.
