Great Coates is a village and civil parish in North East Lincolnshire, England.

It is to the north-west and adjoins the Grimsby urban area, and is served by Great Coates railway station.

[11][n 3] In October 1697 antiquary Abraham de la Pryme recorded the moated site in Great Coates as containing a brick built religious house, with "turrits like the old buildings, and somewhat in the walls of the gaithouse, which seems to have been niches for images, tho' now bricked up".

[n 5] In c. 1887 the village consisted of the church, rectory (early 19th century, now The Old rectory[21]), a Wesleyan chapel, and around 20 dwellings including the substantial Manor House (c. 1878[22]), and Great Coates House, as well as with the station less than 1/2 mile northeast of the traditional centre (church and manor site).

Outside the village the parish was rural, with enclosed fields and drainage channels, with no other habitations of any significance, excluding Pyewipe farm to the northeast.

[23] This development in the parish was mostly unchanged until 1950: the Grimsby and Immingham Electric Railway which passed through the northern part of the parish opened 1912; and terraced housing was built on Woad Lane north and south of the station in the early part of the century.

[24] Additionally a biscuit factory (Watmough and Sons Ltd) had been established east of Woad Road, and north of the railway line by the 1930s.

(See Industry of the South Humber Bank) British Titan Products Co. Ltd. (later BTP Tioxide, closed c. 2009) and CIBA Laboratories Ltd. established large chemical plants in 1949 and 1951 in the northern part of the parish, adjacent to the estuary (see Ciba, Grimsby, and Tioxide, Grimsby) The A180 road was built in the 1970s, and passes through the parish.
