Goltho is a hamlet in the West Lindsey district of Lincolnshire, England. It is situated 1 mile (1.6 km) south-west from Wragby, and 0.5 miles (0.8 km) south from the A158 road.
Wragby and Goltho Limewood Walk, through one of the Lincolnshire Limewoods National Nature Reserves, passes Goltho Hall, Goltho Chapel and Goltho deserted medieval village.
The settlemant has Anglo-Saxon roots. There was a Romano-British settlement at Goltho in the 1st and 2nd centuries.
The origin of the name is uncertain, perhaps from an Old Scandinavian (Viking) first name or the Viking word for "ravine", or as is widely accepted locally, "where the marigolds grow", referred to in Henry Thorold's guide to the redundant St George's Church, Goltho.
The remains of the early medieval village were excavated in the 1970s. A Saxon settlement on the site consisted of two houses; about 850 the site was fortified with the addition of a banked enclosure, and a hall was added. A motte-and-bailey castle was built at Goltho in around 1080.
