Farnsfield is a village and civil parish in Nottinghamshire in Sherwood Forest. It is in the local government district of Newark and Sherwood. The population of the civil parish as at the 2011 Census was 2,731.
In 1944, an RAF Halifax bomber MZ519-LKU crashed on the south side of the village. All on board were killed. The site of the crash has a large memorial.
The village is located 4 miles (6.4 km) north west of Southwell. According to the United Kingdom Census 2001 it had a population of 2,681.
The parish church of St Michael was rebuilt in 1859–60 following a fire.
To the south of the village, along the footpath to Oxton, is a small Roman marching camp, a small Roman fort. One mile south west of the village is a small oval earthwork at Combs Farm. Encircled by a bank and ditch it appears (from excavated material) to be Romano-British in origin. Two ditches in a wood at Camp Hill, 1½ miles north east of Farnsfield are the remaining traces of an Iron Age earthwork, a hillfort, which was estimated in the 18th century to have been 40 acres (16 ha) in area.
There was a tower windmill on Siding Lane (grid reference SK644572) shown on a map of 1898 as an 'old windmill'. It was recorded as a shell in August 1935, with the cap and fantail gone. The mill was owned at some time by a miller called Whitehead, who also milled at Edingley watermill. When in use, it was powered by a gas engine.
