Lincolnshire County Council is the county council that governs the non-metropolitan county of Lincolnshire in England. The non-metropolitan county is smaller than the ceremonial county; the latter additionally includes North Lincolnshire and North East Lincolnshire which are both unitary authorities and therefore independent from the county council.

Lincolnshire is a ceremonial county in the East Midlands and Yorkshire and the Humber regions of England. It is bordered by the East Riding of Yorkshire across the Humber estuary to the north, the North Sea to the east, Norfolk, Cambridgeshire, Northamptonshire and Rutland to the south, and Leicestershire, Nottinghamshire and South Yorkshire to the west. The county town is the city of Lincoln. Lincolnshire is the second largest county in England after North Yorkshire.
