Boston is a market town and inland port located in Lincolnshire, England, situated southeast of Lincoln, east of Nottingham, and northeast of Peterborough. The town serves as the administrative center of the borough of Boston and had a population of 45,339 at the 2021 census, while the broader borough had an estimated population of 66,900 as of 2015.
The town's significance as a port is defined by its connection to the Haven, a waterway that flows approximately 5 miles (8 kilometers) southeast to The Wash, a large bay situated between Lincolnshire and Norfolk on the English coast. This inland port location has historically made Boston an important commercial center for the region.
