Market Rasen is a town and civil parish within the West Lindsey district of Lincolnshire, England. It lies on the River Rase northeast of Lincoln, east of Gainsborough and southwest of Grimsby. Market Rasen has a population of 3,200 people.
The town centre has a homogeneous 19th century red brick appearance of mainly Georgian and Victorian architecture, centred around an active market place dominated by a medieval church albeit much "restored" in the 19th century.
The town is known for its racecourse (Market Rasen Racecourse), as well as its rugby and golf clubs.
The River Rase flows through the town and can be crossed via Jameson Bridge, Caistor Road Bridge and Crane Bridge. The town apparently takes its name from the Anglo-Saxon version of this name, meaning "plank".
Market days are Tuesdays, Fridays and Saturdays. Additionally, on each Tuesday there is an auction of goods and produce, and on the first Tuesday of every month there is a farmers' market. Also every Friday, the WI holds a "country market".
Market Rasen is twinned with the town of Mamers, in the Sarthe region of Pays de la Loire, France.
Market Rasen's community fire and police station (opened December, 2005) is one of the first purpose built combined fire and police stations in the UK. The former police station was built in 1849 and was the third oldest police station still in operational use in the country.
