Harwell is a hamlet in the civil parish of Everton, in Bassetlaw district, northern Nottinghamshire, England. It is located off the A631 road, less than a mile to the northwest of Everton and three miles northeast of Bawtry. Although only a small settlement, historically Harwell had a separate manor. The hamlet had a population of 112 people in the mid 19th century and the Corporation of Newark were lords of the manor at that time. Today, the main feature of Harwell is the Grade II listed Pear Tree House and the Barrow Hills woodland, immediately to the northwest.
