Cowbit (locally pronounced Cubbit) is a village and civil parish in the South Holland district of Lincolnshire, England.
Cowbit Grade I listed Anglican parish church is dedicated to St Mary. The church was built on a small scale in the 14th century by Prior de Moulton of Spalding. A chancel and Perpendicular tower were added by Bishop Russell of Lincoln in 1487. Restoration was carried out in 1882. A Wesleyan chapel was built in 1842, and rebuilt in 1861. To the south, on the road to the hamlet of Peak Hill, is a stone named after St Guthlac, being a boundary marker for the earlier lands of Crowland Abbey.
The village contains a Grade II listed early 19th-century mill, a Church of England primary school, public play area, village hall, a garage, and a village store.
Cowbit previously had a railway station on Spalding to March line; the line is no longer in use.
Cowbit Wash lies to the west of the village, extends 8 miles (13 km) from north to south, and is nearly 1 mile (1.6 km) broad. Mainly arable land, it is a flood plain for the navigable River Welland, separated from Cowbit by an earth bank, Barrier Bank, that carries an unclassified road, the former A1073. Previously Welland overflow regularly flooded the Wash, the water freezing-over during winter allowing for ice skating and skating championships. A relief channel (Coronation Channel) for the Welland at Spalding has made Cowbit Wash obsolete as a flood plain since the 1950s.
Since Queen Victoria’s Diamond Jubilee in 1897 there has been a punt gun salute over Cowbit Wash every coronation and jubilee, concurrent with gun salutes in London, including the June 2012 Diamond Jubilee of Elizabeth II.
