Bigby is a village and civil parish in the West Lindsey district of Lincolnshire, England. It lies about south from the Humber Bridge, and east from the town of Brigg. The village lies in the Lincolnshire Wolds, a designated Area of Outstanding Natural Beauty and close to the administrative border with North Lincolnshire. The hamlets of Kettleby and Kettleby Thorpe lie within the parish, and that of Somerby is situated nearby.
According to the 2001 census Bigby had a population of 234, though this has increased because of the new Bigby Green housing development.
The name Bigby comes from an Old Norse personal name Bekki + Old Norse býr, meaning "settlement" or "farmstead".
Bigby is recorded in the Domesday account as "Bechebi", and the Lord of the manor was William son of Nigel.
The local Anglican parish church is a Grade I listed building dedicated to All Saints. It dates from the 12th century, with later additions and restorations in 1779 and 1878. On the north side of the chancel is a large alabaster tomb to Sir Robert Tyrwhit of Kettleby hamlet, who died in 1581, and his wife. To the east is a monument to Sir Robert Tyrwhit of Kettleby, who died in 1617, and Lady Bridget Manners his wife who died in 1604.
Bigby is one of four Thankful Villages in Lincolnshire, because it lost no men in World War I. There is a war memorial in the parish churchyard in remembrance of two local men who died during World War II.
Pingley Farm, or Camp 81, was the site of a second world war Prisoner-of-war camp. Purpose-built to house 750 low-risk prisoners, by May 1946 Pingley camp actually held 984. It still exists today but is derelict.
