Marfleet is a suburb of Kingston upon Hull, near the A1033 road, in the East Riding of Yorkshire, England. It was served by Marfleet railway station on the Hull and Holderness Railway until it closed in 1964. Marfleet has a school, a place of worship and a post office.
Historically, Marfleet was an ecclesiastical parish in the wapentake of Holderness.
In 1974 most of what had been the East Riding of Yorkshire was joined with the northern part of Lincolnshire to became a new English county named Humberside. The urban and rural districts of the former counties were abolished and Humberside was divided into non-metropolitan districts. The new organization did not meet with the pleasure of the local citizenry and Humberside was wound up in 1996. The area north of the River Humber was separated into two "unitary authorities"—Kingston-upon-Hull covering the former City of Hull and its closest environs, and the less urban section which, once again, named itself the East Riding of Yorkshire.
