Glentham is a village and civil parish in the West Lindsey district of Lincolnshire, England.

[1] Glentham was mentioned in the Domesday Book of 1086, as being in the Aslacoe hundred in the West Riding of Lindsey.

At the west of the church is a mutilated 14th-century brass effigy of a female;[4] previously known as "Molly Grime", it was, up to 1832, washed every Good Friday by seven old maids.

[7] At that time much land in the area was given over to pasture, while main crops grown were wheat, barley and beans.
